In precision assembly and heavy lifting operations, traditional 50/60 Hz electric hoists often suffer from harsh startup shocks, noticeable swinging, poor synchronization, and rapid brake wear. A manufacturing company addressed these issues by upgrading their hoists with variable frequency drives (VFDs), significantly improving performance and reliability. · The VFD allows smooth control of motor acceleration and deceleration. This eliminates the sudden jolt at startup and the abrupt stop during braking. As a result, mechanical shock drops by about 70%, which greatly extends the life of chains and structural parts. · Because the VFD adjusts power output based on load, multiple hoist points can move in sync. After the upgrade, the height difference between two lifting points stays within ±3 mm. The load remains level automatically after positioning, boosting work efficiency by roughly 25%. · Braking also becomes far more dependable. The system holds the load steady at zero speed before engaging the mechanical brake. This cuts brake pad wear by over 90%. Even if power fails, the motor maintains holding torque to prevent the hook from slipping—making the whole operation safer. Overall, variable frequency technology transforms a basic electric hoist from a simple lifting tool into a precise motion system. It directly tackles three key problems: mechanical shock, inaccurate positioning, and over-reliance on mechanical brakes. For demanding lifting tasks, this upgrade offers a reliable and cost-effective solution.

In today’s rapidly evolving and fiercely competitive steel industry, production efficiency and product quality remain the core elements of enterprise competitiveness. Today, we are excited to share a successful case study showcasing how V&T’s V9-H series inverters transformed a 1250 cold roll forming line in a steel mill—demonstrating how this upgrade enabled the production line to achieve a remarkable transformation and embark on a new journey toward high-efficiency manufacturing. The 1250 cold roll forming line is an automated production system designed for processing steel coils with a maximum width of 1250 mm. Functioning like a precision steel-shaping factory, it continuously forms hot-rolled or cold-rolled steel strips into various profiled sections through a cold roll forming process at ambient temperature. The line integrates multiple coordinated units—including uncoiling and feeding, leveling and shearing, cold forming, cut-to-length, and control systems. Its core principle relies on progressive plastic deformation via multiple roll stands to gradually bend the 1250 mm-wide steel strip into the desired cross-sectional profile. Throughout this process, an automated control system ensures precise speed synchronization among all units, accurate dimensional control, and real-time quality monitoring—guaranteeing consistently high-quality output. Urgent Need for Retrofit: The “Growing Pains” of an Aging Line However, as market demands evolve and production pace accelerates, the legacy 1250 cold roll forming line began revealing significant limitations. Mechanical components of the roll stands had aged due to prolonged use, the original inverters were undersized in power rating, and the system operated in open-loop mode using only Modbus RTU (RS485) communication for speed control. These issues led to sluggish mechanical response and poor speed synchronization across the multiple drive shafts of the roll stands. Operators were forced to constantly and manually fine-tune speed ratios between drive axes just to maintain minimal synchronization. This not only imposed heavy labor demands but also severely compromised production speed, output capacity, and product quality—making a comprehensive upgrade imperative. V&T V9-H Series Inverters: The “Key” to Transformation To better adapt to changing market conditions and enhance the overall capability of the cold roll forming line, a targeted retrofit of the roll stand drive system was launched—with V&T’s V9-H series inverters playing a pivotal role. On the mechanical side, motors, gearboxes, and drive shafts of the roll stands underwent thorough inspection and precise realignment. Encoders were added to the motors to enable closed-loop control, significantly improving motor responsiveness and laying a solid mechanical foundation for higher-speed operation. On the electrical side, modern intelligent control components—including an HMI touchscreen, PLC, and V&T V9-H inverters—were integra...

Three approaches have been adopted for the variable frequency speed control retrofit of sucker rod pumps 1.Variable Frequency Drive (VFD) with Braking Unit Control By adding a braking resistor and a braking unit to both ends of the DC bus in the main circuit of the VFD (this method has a high cost-effectiveness ratio), due to the need for high torque during the startup and ascending phase of the sucker rod pump, and during the descending phase, the motor is in a power generation state. The most critical part is the descending phase, which is a continuous operation process, while adjusting the reciprocating motion per minute according to the oil viscosity, well depth, and production rate, causing the motor to enter a regenerative power generation state, feeding excess energy back to the grid, leading to an increase in the voltage on the DC bus of the main circuit of the VFD. Without a path for electrical energy to flow back to the grid, it must be dissipated locally using resistors. This is why we must use a braking unit and braking resistor on the VFD, and our company's high-power VFDs can have built-in braking units, fully achieving the desired control effect. 2.VFD with Regenerative Feedback Unit Control A regenerative feedback unit is added to the DC circuit of the VFD to feed the electrical energy generated during the motor’s regenerative (power generation) state back into the grid. 3.VFD Automatic Intelligent Control — No Braking Unit or Regenerative Feedback Unit Required In general, no braking unit or regenerative feedback unit is required. The VFD can automatically adjust its operation according to the working conditions of the beam pumping unit, resulting in lower system cost, higher reliability, reduced harmonic pollution, and better adaptability to operating voltage variations. Two-Location Control for the Variable Frequency Speed Control System As per requirements, each variable frequency speed control cabinet is equipped with one VFD, which automatically controls the motor in open-loop speed mode. The control cabinet features a switch between line-frequency (bypass) and variable-frequency operation, offering three positions: line-frequency, variable-frequency, and stop—ensuring simple and convenient operation. When switched to variable-frequency mode, the VFD runs automatically. Speed adjustment is achieved by feeding an analog signal from the potentiometer on the control cabinet to the AI1 terminal of the VFD. During operation, real-time parameters such as current, voltage, power, and frequency can be viewed directly on the VFD’s display panel. For upper-level (remote) control, no switching is required—the VFD can be started and stopped directly, and its operating status and running frequency can be set remotely. Current operational data can also be copied and exported into documentation. Product Advantages: Comprehensive protection against external faults, including short circuit, phase loss, overload, and phase imbalance; Hi...
On November 28, 2025, V&T officially launched its initiative to establish a management system aligned with the ISO/SAE 21434 standard, "Road Vehicles – Cybersecurity Engineering." This move is not a sudden leap of disruptive innovation within the industry, but rather stems from long-term observation and careful assessment of automotive intelligence trends. The goal is to enhance cybersecurity resilience throughout the entire product lifecycle through a systematic framework, thereby providing more reliable foundational support for product safety in the era of intelligent connected vehicles. As 5G, AI, and IoT technologies continue to converge, automobiles are evolving from traditional means of transportation into mobile intelligent terminals. While innovations such as in-vehicle infotainment systems and advanced driver-assistance functions significantly improve user experience, they also introduce potential risks—including data breaches and unauthorized remote control. Industry statistics indicate a marked increase in global automotive cybersecurity incidents in recent years, with hackers employing increasingly sophisticated attack methods that legacy functional safety standards can no longer adequately address. Against this backdrop, ISO/SAE 21434—the world’s first international standard for automotive cybersecurity—offers critical value by embedding cybersecurity management into every phase of a vehicle’s lifecycle: design, development, production, operation, maintenance, and end-of-life disposal. Leveraging Threat Analysis and Risk Assessment (TARA) methodologies, the standard enables organizations to identify attack surfaces, quantify risk levels, and implement targeted mitigation strategies. For instance, regarding communication interfaces between in-vehicle systems and external devices, the standard mandates encrypted communications and access control mechanisms to prevent data theft or tampering. In an industry landscape often fixated on “technological breakthroughs,” V&T’s approach stands out for its restraint. Company leadership stated, “There is no such thing as ‘absolute security’ in cybersecurity, but we can continuously reduce the probability of incidents through iterative improvements. We prefer to be long-term thinkers, making steady investments to create replicable, practical examples for the industry.” This philosophy aligns closely with broader industry trends. Under United Nations Regulation No. 155 (UN R155), starting in 2024, all vehicles and components exported to Europe must obtain certification under a Cybersecurity Management System (CSMS)—with ISO/SAE 21434 serving as its core supporting standard. V&T’s systematic implementation thus responds proactively to international compliance requirements while demonstrating its commitment to advancing high-quality development in China’s intelligent connected vehicle sector. In the race toward intelligent mobility, cybersecurity has become an invisible yet existential th...

The mine hoist plays a central role in coal mining. It moves coal and waste rock from underground workings to the surface. It also carries workers, supplies, and equipment up and down the mine. Older hoists use wound-rotor motors with resistor-based speed control. This method wastes a lot of energy. Nearly one-third of the electricity is lost as heat in the resistors. Speed regulation is uneven and inefficient. At lower speeds, the motor performs poorly. It becomes weak and unsteady. The equipment suffers from heavy shocks. This leads to breakdowns and accidents. It also requires constant upkeep. Parts like contactors and brushes wear out quickly. The mechanical brake system takes a lot of abuse. Maintenance is expensive and time-consuming. Application of VFDs in Mine Hoist Using a V&T VFD changes everything. It provides strong torque even at very low speeds. The hoist starts and stops smoothly. There’s no creeping or sudden jerks. Everything runs more steadily. The speed adjusts smoothly without steps. There’s less shock to the gearbox and brake. That means less wear and longer life for the equipment. There’s no need for old-style contactors or brushes. Simple squirrel-cage motors work perfectly. Maintenance becomes much easier. The drive also includes full protection and monitoring. Used together with a PLC, it makes the whole system far more reliable. And best of all—it saves energy. No more wasting power on resistance banks. With the V&T drive, mine hoists run safer, smoother, and more efficiently. They also cost less to maintain. It’s a modern solution that helps keep mining operations running continuously.
In industrial production, the efficient and stable operation of speed control systems is paramount. Traditional systems often face challenges like low power factor, difficulty in energy regeneration, and significant harmonic interference, constraining production efficiency and quality. Active Front End (AFE) technology provides an effective solution to these issues. V&T's DTS800 Series AFE products are designed precisely to meet the demands of high-performance speed control. An AFE is a drive unit that supplies DC power to a variable frequency drive (VFD) via PWM rectification while simultaneously regenerating braking energy from the motor back to the grid. Together with the motor drive section, it forms a complete AFE speed control system, enabling four-quadrant operation for motor-driven speed regulation. DTS800 Series Core Components: DTS800-R AFE Rectifier/Regeneration Module: Supports constant voltage, constant current, and constant power modes. Performs sinusoidal PWM rectification and energy regeneration. Ensures the resulting AFE system delivers low grid-side current harmonics. DTS800-H Drive Inverter Module: Employs independently developed DTC (Direct Torque Control) technology. Delivers rapid torque response and high speed regulation accuracy. Supports DTC control with or without an encoder. Unique DTC technology ensures excellent low-speed torque and fast torque response even during encoderless operation Wide Application Scope: The DTS800 Series AFE products are ideally suited for applications requiring stable power supply and efficient regeneration of motor braking energy to the grid, including: Crane equipment, centrifugal equipment, oilfield equipment, experimental test platform, opposite drive system, downhill conveyor belt, winch. The V&T DTS800 Series AFE products demonstrate solid and reliable characteristics across key aspects: four-quadrant operation capability, energy regeneration efficiency, control algorithm implementation, ease of use, communication support, and structural design. Their robust and high-performance nature precisely meets the stringent requirements of modern industrial production for speed control systems while aligning with industry trends.
In factories, inverters are key for controlling motors, helping them run at the right speed and save energy. Sometimes, several motors need to run at exactly the same speed, or work together to move one big thing, like a long production line. Using one bigger inverter to control multiple motors at once can be a cheaper and smarter way to do this. How you start the motors decides which method you use: starting them all together, or starting them one after another. Method 1: Starting and Stopping Together When to Use It: When motors (especially identical ones, made by the same factory) must run at the same speed, perfectly in sync. How It Works: One large inverter powers all the motors simultaneously. They start and stop together. The Big Plus: It saves money and gets the job done well. Picking the Right Inverter: The inverter must be big enough to handle all motors combined. The inverter must be strong enough (provide enough electrical current) for all the motors. Its rated current needs to be at least 1.2 times the total current all the motors use. Important Things to Remember: Control Mode: You must use open-loop V/F control. Other smarter controls need details about one specific motor and won't work well here. Matching Motors: The motors shouldn't be too different in size. It's best if they are the same model, made by the same company, even the same batch. This helps them run together smoothly. Watch the Wires: Keep all the wires running from the inverter to the motors as short as possible. Long wires cause problems. If the total wire length is too long, you might need extra parts (like an output reactor or filter) near the inverter. Protect Each Motor: Every single motor needs its own thermal overload protector (like a heat-sensing switch) right before it. This protects it if it gets too hot. Stopping Fast: If the motors need to stop very quickly, you'll likely need a special braking unit and resistor. Some smaller inverters have the braking unit built in—just add the resistor. Method 2: Starting One After Another When to Use It: When different parts of a machine need to start at different times. How It Works: The inverter acts like a power source. You switch its power to one motor at a time. The Big Plus: You need fewer inverters, saving cost. The Critical Rule: Never, ever let two or more motors run from the inverter at the same time. If this happens, the inverter will be overloaded and likely damaged. In Summary Using one inverter for multiple motors (starting together or separately) is a smart, money-saving trick in factories. To make it work safely and well, you must pick an inverter that's powerful enough and follow the specific rules for how you start the motors (like using the right control mode, matching the motors, keeping wires short, adding individual motor protection, and preventing overlap). Doing this right means reliable equipment and lower costs.
V&T, working with Zhongchuang Minghui, has successfully installed its new grab crane control system at Dongdaqiao Station and Future Science City Station. Customers report good results. Solving Old Problems: The older way to run these cranes used cam controllers, contactors, and resistors. This method caused several issues: machines broke down often, wiring was complicated, they wasted power, and operators couldn't adjust speeds very well. How V&T's Frequency Converters Help: Smarter Grab Control: The operator sends a signal. The control system (PLC) then checks the motors' current, torque, and speed. V&T frequency converters adjust the motors' speed and power smoothly. This keeps the grab bucket moving efficiently and stops material from spilling. Even if mistakes happen: If the grab opens too soon while lifting, the operator doesn't panic. Using low speeds 1 or 2 for about ten seconds lets the grab close itself. This makes the job easier and needs less skill. Better Visibility for High Work: When the crane works high up, operators struggle to see the grab bucket clearly. This slows things down. V&T's system shows everything important on a touchscreen. Operators work faster and don't need years of experience. Smooth Speed Changes & Savings: The grab open/close motor uses 3 speed settings. Other motors (trolley, bridge, auxiliary hoist) use 4 settings. V&T frequency converters make all speed changes very smooth. Starting is gentle, low speeds are steady, and less electricity is wasted as heat. This is easier on the motors, especially with lots of stopping and starting, helping them last longer. A shared power setup (DC bus) for the main and travel drives uses fewer cabinets, lowering the customer's costs. Easy Monitoring & Fixes: All V&T frequency converters connect to the PLC using communication cables. The PLC connects to the touchscreen. Operators see the system status and data on the screen. They can also change some settings there easily. If something goes wrong, the screen shows exactly where the problem is, including specific error messages from the frequency converters. This helps technicians fix things fast. The Result: V&T frequency converters provide smooth starting, precise speed control, and strong protection. Combined with the PLC, they create a safer, more accurate, and efficient way to run grab cranes. The clear touchscreen display is key. The success at Dongdaqiao and Future Science City shows V&T's system improves crane automation, efficiency, and ease of use.

In modern building material factories, block making machines are the main workhorses. They run automatically, make many kinds of blocks or bricks, and produce large quantities. The part that shakes the mix to form the block is the heart of these machines. How well this shaking part works decides how good the machine is and how good the blocks turn out. For a long time, these shakers used motors or hydraulic pumps running at fixed speeds. But now, using a variable frequency drive (VFD) to control the motor speed for the shaker has become the better way. Many machine makers prefer this method. Here's why VFDs make a big difference: Better Control for Better Blocks: VFDs let workers easily change how fast the shaker vibrates and how strong it shakes. The machine can remember the best shaking settings for different block types. Workers can control starting, speeding up, slowing down, and stopping smoothly. This makes blocks much denser and gives them a smoother, nicer finish. Faster Work, More Blocks: The shaking part speeds up and slows down very quickly with a VFD. This makes each block form faster. Because blocks form quicker, the whole machine can make more blocks every hour. Gentler Starts, Less Wear: VFDs let the motor start very gently. This uses less power at startup and doesn't stress the electricity supply. It also means less sudden force hitting the machine parts. This causes less damage over time, meaning fewer breakdowns and cheaper repairs. Saves Power, Runs Cooler: VFDs manage the motor's power more efficiently. Less power gets wasted, saving electricity. The motor also doesn't get as hot, which helps it last longer and work reliably. Stable Power, Fewer Stops: VFDs have built-in voltage control (called AVR). Even if the building's power voltage gets low, the VFD can still give the motor enough steady power to work. This keeps the machine running and prevents unexpected stops. Easy to Use: Systems using VFDs are simple to operate and adjust. They need fewer wires to connect and have special controls that make setting things up easier. Why VFDs Matter: Putting a VFD on the shaker motor isn't just about changing speed. It makes the whole block making machine work better. Blocks come out stronger and look nicer. The machine makes more blocks per hour. It uses less electricity and needs less fixing. Because the machine runs more smoothly and stops less often, it's a smarter choice for factories wanting good, reliable equipment. VFD technology is now key for modern, efficient block making.
Introduction Slitting machines are key equipment in paper and packaging plants. They cut wide rolls of paper or film into many narrow strips. Keeping the material tension steady is very important. It makes sure the cuts are clean and the widths are exact. Old slitting machines often use magnetic particle clutches to control tension. These clutches work well for small tensions at slow speeds. But they cause problems at high speeds. The friction creates a lot of heat. This heat shortens the clutch life and limits how fast the machine can run. Challenges in the Pressroom Running these machines in a busy printing factory is hard. There are several problems: Sudden Load Changes: Starting, stopping, and changing rolls puts big, instant stress on the motor. Many drives can't handle this shock. They stop working. Tough Environment: The air is full of dust. Temperatures get hot. These conditions are hard on electrical parts. Need for Precision Control: Sometimes three motors work together on one machine. They must run at exactly the right speeds. If they don't, the cut material won't be straight or the same width. How V&T Drives Help V&T drives solve these pressroom problems effectively: They Handle Heavy Shocks: V&T drives manage the big load spikes during start, stop, and roll changes. They keep the machine running. Other drives often trip and cause shutdowns. They Work in Tough Conditions: V&T drives are sealed against dust. Their cooling works well, even when it's hot. We know this works. These drives have run reliably in printing factories for 12 years. Dust and heat haven't caused major breakdowns. They Control Speed Precisely: V&T drives control motor speed and power very accurately. When multiple motors need to work together smoothly, these drives make it happen. This keeps the material tension steady. The result? Material is cut cleanly and evenly, every time. The Benefits Using V&T drives on slitters fixes issues with older clutch systems, especially at higher speeds and with sudden loads. They also handle the difficult pressroom environment well. Customers get important advantages: More Machine Uptime: Fewer stops from load shocks or environment problems mean the machine runs longer. Better Quality Cuts: Precise speed and tension control ensure accurate sizes and clean edges. Built for the Job: These drives handle common pressroom dust and heat, lasting longer. Potential for Faster Speeds: They provide the stable power needed to try running slitters faster than older clutches allowed. Conclusion Slitting machines need drives that are tough, reliable, and precise. V&T drives deliver on all three. They handle shocks, work in dusty heat, and control speed accurately. Their real-world performance is proven. For 12 years in actual pressrooms, they've been reliable. V&T drives are a solid choice. They help customers get more from their slitting machines.
Today, clean air and efficient operation matter more than ever. V&T proudly introduces our advanced Oil-Free Scroll Air Compressor. This innovative machine is made for places where air quality is critical. It's the perfect power source for labs, healthc What is an Oil-Free Scroll Air Compressor? This compressor is a big step forward in air technology. Unlike old piston compressors, it doesn't need oil for lubrication. It uses a special scroll movement to squeeze the air. This guarantees the air coming out is completely oil-free. You get cleaner air, less maintenance, and no risk of oil contamination. It gives you peace of mind. How It Works: The Smart Heart of the Machine The orbiting scroll rotates in the order shown in Figure 1-2-3-4. The crescent-shaped compression chamber gradually decreases in volume, compressing the gas inside. The compressed gas is then discharged from the center of the fixed scroll. Two precise spiral scrolls work together: Fixed Scroll: This part stays still. It forms the main compression chamber. Moving Scroll: A motor drives this part. It orbits in a tight circle around the fixed scroll. Air gets pulled in. It gets trapped between these two scrolls. The moving scroll squeezes the air pockets smaller and smaller. Pressure builds steadily. Finally, clean, compressed air pushes out through the center. The scrolls never touch metal-to-metal. So, it needs no oil at all. This stops oil from ever getting into your air. Why Choose Our Oil-Free Scroll Compressor? Perfectly Clean Air: Meets the strict ISO 8573-1 Class 0 standard for oil-free air. This means absolutely no oil, mist, or vapor in your air supply. Gives you zero-risk air for critical jobs: precision labs, sterile drug making, safe food production, and high-end electronics. Super Quiet Operation: The unique scroll design doesn't need parts to touch, so it runs much quieter. It works smoothly and quietly. Fits right into noise-sensitive places like labs, hospital rooms, cleanrooms, or offices. Makes the workspace better. Great Energy Savings: Squeezes air in one smooth, continuous motion. This wastes less energy. Uses less power than old piston compressors. Saves you significant money on electricity bills over time. Good for your budget and the planet. Compact Size, Saves Space: Built in a smart, modular way. It's small and simple. Fits easily under lab benches, in tight equipment corners, or other small spots. Makes the best use of your valuable space. Built to Last, Easy to Care For: The oil-free design means fewer parts can break. It runs reliably for a long time. Maintenance is very simple. Mainly, just change the air filter regularly. Saves you time and money on upkeep.
XCMG Heavy Duty's electric mining dump trucks are now running in mines in Southwest China. These trucks use V&T's special motor controller. The order is worth about 16 million yuan. Mine operators chose these trucks because they handle tough jobs well and meet special needs. This is a big step towards cleaner "green mines". These electric trucks are as strong as XCMG's older fuel-powered ones. They have a tough cargo box, strong frame parts, and a solid body. They carry very heavy loads well. The V&T controller helps the transmission learn by itself. It learns during gear changes and when the truck powers down. This fixes problems caused by wear over time. Shifting gears becomes smooth and exact. The truck works reliably in many situations – flat ground, hills, or water. You don't need to keep resetting its software. Driving is comfortable too, with adjustable seats, strong springs, and a cab designed for a good view. Being electric, these trucks are cleaner, quieter, and save energy. Their special motor braking system captures energy when slowing down. It saves over 10% of the energy this way. The whole system runs very efficiently, over 80% of the time. The V&T controller makes everything work together better – the motor, the gearbox, and the battery. This smart teamwork means the truck uses at least 5% less power than similar trucks. On regular mine routes, it learns from data about how the truck moves. Then it figures out the best times to shift gears and how to use energy, saving even more power. Many electric vehicles struggle with how far they can go and how strong they are. XCMG's electric mining truck handles this well. It uses safe and powerful lithium iron phosphate batteries. These batteries hold nearly 200 kilowatt-hours of power. Clever control helps the truck go further on a charge. It starts with huge force – up to 18,000 Newton-meters of torque. It can go from 0 to 50 km/h in under 20 seconds. The truck uses a tough 7-speed gearbox, proven on 100-ton trucks. This gearbox runs cool, works well, and is simple. The V&T controller automatically picks the right gear for the hill slope and the truck's weight. This keeps the pulling power strong. The truck can climb very steep slopes, over 45%. Even fully loaded, it climbs slopes steeper than 30%. This means it easily handles rough mine terrain.
Foshan, Guangdong recently received a group of new eco-friendly buses. Two hundred brand-new hydrogen fuel buses have been delivered. They will soon run on roads across the Greater Bay Area. These buses use electric motor controllers from Shenzhen V&T Technologies Co., Ltd. (called V&T here). When these buses start operating, they will cut down harmful particles (called PM2.5) in bus exhaust. This helps keep the air fresh in the Greater Bay Area cities. V&T is an important maker of motor controllers for new energy vehicles. They worked closely on this hydrogen bus project. V&T supplied key motor control systems for the buses. This makes sure the buses’ power source works well and reliably. V&T showed strong technical skills. They also delivered parts fast enough to keep up with the bus maker’s production. The bus maker praised V&T for this good work. Right now, all 200 hydrogen buses have their license plates. This means they can soon begin carrying passengers between cities in the Greater Bay Area. Adding these zero-emission buses does more than just update public transport. It’s a solid step toward cleaner air. These buses will truly help reduce PM2.5 levels in our air. They’ll make the air cleaner for cities to "breathe." They’ll help protect the environment we all share.
Recently, a fleet of 18-meter-long pure electric BRT buses equipped with V&T electric vehicle motor controllers has been put into large-scale operation on the main roads of a coastal city. These giants not only practice green and low-carbon concepts through zero emissions but also significantly enhance urban public transport capacity with their efficient and safe operations, effectively alleviating passenger flow pressure during peak hours, becoming an eye-catching new scene on the streets. As urban areas continue to expand, road traffic pressures are increasing day by day. Apart from rail transit, developing Bus Rapid Transit (BRT) systems is becoming an increasingly popular choice for many cities and even an important symbol of modern urban construction. So, what is BRT? BRT, or Bus Rapid Transit, is a new type of high-capacity public transportation method that integrates modern bus technology and intelligent traffic management. It features dedicated roads and modern stations, offering high operational efficiency, often referred to as "metro on the ground." The aim of BRT is to provide convenient passenger services comparable to those of rail transit. The application of this system plays a significant role in improving the efficiency of bus operations and alleviating urban peak hour congestion. Industry observers point out that with more cities promoting the electrification and efficiency of buses, vehicles using V&T electric control solutions are expected to appear in more cities in the future. They will undertake the heavy responsibility of citizens' daily commutes, contributing to the upgrade and image enhancement of the urban transportation network.

Variable Frequency Drives (VFDs) play a crucial role in the operation of cranes and hoists. They are used to precisely control the speed and torque of electric motors, thereby enhancing operational efficiency and control accuracy. On March 16, with the final cable strand accurately positioned, the main cable pulling work for Fenglin Special Bridge on the Xingyi Belt Expressway was successfully completed. This marked a significant milestone in the bridge’s superstructure construction and laid a solid foundation for achieving the goal of full completion by the end of 2020. The high-performance, high-power variable frequency drives (VFDs) provided by V&T Power played an important role in ensuring the smooth progress of the bridge’s main cable installation due to their stable performance and excellent reliability. Fenglin Special Bridge is China’s first large-span steel-concrete composite beam suspension bridge built in mountainous terrain. The vertical height from the bridge deck to the valley floor reaches 364.2 meters—equivalent to approximately 120 stories. The lifting of the prefabricated central crossbeam at Tower No. 4, weighing up to 1,470 tons, set a world record for the heaviest prefabricated concrete component hoisting in mountain canyon bridge construction. Main cable construction is one of the most critical and technically challenging processes in the building of Fenglin Bridge, as it forms the primary load-bearing system of a suspension bridge. The bridge has two main cables—one on each side—each approximately 971 meters long, with a total weight of 4,131 tons. Each single cable consists of 131 strands (including 4 backstays), and each strand is made up of 91 zinc-aluminum-magnesium-coated steel wires with a diameter of 5.45 mm. The maximum weight of a single cable strand is about 16.4 tons. The winch systems installed on both sides of the bridge have extremely high requirements for the performance, stability, and reliability of the VFDs. The V&T V6-H torque vector control VFD performed exceptionally well, playing a key role in the main cable pulling process. Its advanced technology and product stability have received high praise and recognition from users. During equipment commissioning, Ma, a V&T technical engineer, had to walk across the “catwalk” on the bridge. He said: “Standing over 360 meters above the valley floor just thinking about it makes my legs weak. This time really pushed my fear of heights to the limit. Walking on the catwalk feels like walking through clouds—nervous yet incredibly impressive. I deeply admire the hard work, selflessness, and perseverance of the bridge builders, who embody the spirit of the ‘Iron Army.’” Since the start of construction, Fenglin Special Bridge has been widely covered by major media outlets including CCTV's *News Broadcast*, *Morning News*, *Great Transportation of China*, Xinhua News Agency, People's Daily Online, and local...

V&T’s high-power electric vehicle motor controller has successfully entered the “Roof of the World” in large quantities. The rugged quality of V&T products has been proven in mine sites in Qinghai and Xizang. Recently, 90-ton all-electric wide-body dump trucks equipped with V&T motor controllers have begun operating in high-altitude mining areas in Qinghai (about 4,300 meters above sea level) and Xizang (about 5,000 meters above sea level). This success brings more confidence to China’s new energy vehicle industry and also inspires V&T to keep pushing forward and aiming higher. At a large mine in Xizang, at an average altitude of 5,000 meters, traditional fuel-powered trucks used to carry rock and ore from mountain tops down. In this environment, low air pressure causes poor engine intake, incomplete combustion, reduced power, higher fuel consumption, and greater pollution. Now, a group of energy-saving and eco-friendly 90-ton all-electric wide-body dump trucks has arrived. These vehicles solve the problems of weak power and high fuel cost in high-altitude, low-oxygen conditions. The truck automatically adjusts between single or dual motors based on real-time working conditions through the high-power V&T motor controller. This lowers driver workload, improves efficiency, and helps protect the environment. The dual-motor braking system can recover up to 580 kW of energy, making full use of downhill energy and improving overall economic performance for customers. In these mines, trucks often run heavily loaded downhill for long periods. When the driver brakes, the mechanical energy is turned into electricity by the V&T motor and controller system and stored back into the battery. According to the fleet manager, on a 4.5-kilometer route, each electric truck saves over 2,000 yuan per day compared to fuel trucks—around 25 to 30 trips. Working together with vehicle manufacturers, V&T shows strong reliability under extreme conditions like high altitude and steep slopes. It reflects China’s progress in electric mining trucks and motor control technology. Through real action, V&T supports the mining industry with a new driving force and contributes to greener, safer, and more efficient mining transport.

A giant mining truck that can generate electricity and make money The advent and successful application of a V&T new energy mining vehicle motor controller has greatly reduced the cost of mining and transportation, and installed a new engine for the development of the mining industry. Wide-body mining vehicles are heavy vehicles used in large open-pit mines to complete rock and earth stripping and ore transportation tasks. They travel back and forth between mining sites and unloading sites, and have the characteristics of short transportation distance and heavy load. Fuel consumption accounts for about 60% to 80% of the total transportation cost. How to control fuel costs has become a key issue in determining the profit and loss of transportation companies. V&T new energy mining vehicle motor controller has been successfully applied in batches to a domestic hybrid "giant" mining vehicle. Its advent and successful application have greatly reduced the cost of mining and transportation, and installed a new engine for the development of the mining industry. The "Big Mac" mining truck is equipped with a V&T motor controller and a four-in-one integrated controller, which integrates drive motor control, oil pump, air pump, high-voltage power distribution, DCDC, brake power generation feedback and charging functions. It has high power density and meets the characteristics of low-speed and high-torque of the drive motor, heavy-load climbing and heavy-load downhill braking power generation requirements, realizing safe and efficient operation under all-weather conditions in different regions. As the depth of open-pit mining increases year by year, the phenomenon of large slopes and multiple bends makes mining operations increasingly difficult. About 50% of a transportation cycle is uphill and 50% is downhill. During the heavy-load downhill braking process, the new energy mining truck uses the V&T motor controller to perform feedback braking and power generation to achieve energy recovery and save energy. The power consumption is about half that of traditional vehicles. There is huge room for future development of electric wide-body mining trucks. V&T is willing to use its excellent wide-body mining truck electronic control solutions and successful application experience to make new contributions to the construction of "green" mines in my country!
