I. Technics Introduction The spinning-frame is main spinning machine. The yield and quality of spun yarn comprehensively reflects merits and shortcomings of each working procedure in spinning process. The spinning-frame's production unit is spindle. The yield (kg) per thousand spindle hour is frequently used to measure production-level of spinning-frame. The spinning mill's production scale is represented by total spindles of spinning-frame. The spinning yarn on each spindle would be broken for all kinds of reasons. The end breakage rate is frequently represented by number of broken ends per thousand spindle hour. The end breakage rate affects labour productivity, equipment productivity, spun yarn quality and workshop dust content. The spinning-frame is a machine with the most dissipation energy in spinning. Decreasing end breakage rate and energy saving is a technical level mark of spinning-frame. The textile inverter is rich in application experience in spinning industry，especially in spinning-frame industry. Through multiyear research，V&T understands each process flow and launches the dedicated inverter special for spinning-frame. Its technics features are as follows： a.Small yarn stage occupies 15% of total length，but end breakage rate is about 70%. The speed at small yarn stage can be decreased appropriately according to yarn status so as to decrease end breakage rate. b. Middle yarn stage occupies 80% of total length. The end breaking is extremely few，occupying around 10%. The motor speed can be increased appropriately at this stage so as to improve efficiency. c. Large yarn stage occupies 5% of total length. The end breaking is 20%. The motor rotation speed can be decreased appropriately at large yarn stage to decrease end breakage rate and improve the product quality. The technics curve control at multistage speeds can be performed for frequency converter according to spinning-frame features. The running schematic diagram is shown in Fig. 1. Fig. 1 Running schematic diagram of spinning-frame It can be known from Fig. 1 that low speed running of frequency inverter is effective at initial period and frequency speed drive outputs low speed running command； After low speed running command is cancelled，the frequency converter runs according to a curve set by multistage speed technics. The frequency converter accelerates to multistage speed 1 for running. Along with increase of the first stage length，frequency gradually increases. After running of the first stage length is completed，frequency converter runs at multistage speed frequency 2. This process changes at uniform speed； Each section yarn length setting is increased in sequence. The parameter design can be set from full yarn length commencement，gradually decreasing each section length setting. Each section length is limited by the next section length. It satisfies the following relation：the first length < the second length < the third length…….< The 13th lengthMonitoring for...
AC drives or Variable frequency drives control speed, torque, acceleration, deceleration, and rotation direction of AC motors. AC drives save energy by tailoring the power delivered to meet the actual load requirements. AC drives replace mechanical gearboxes, belts, hydraulic couplings, DC drives, servo drives, or eddy current drives in many situations. AC drives provide an accurate and wide range of smooth and step-less control of motor speed and torque in a highly efficient, low maintenance, compact size package. AC drives also provide versatile built-in functions, complex control, and networking capabilities and freedom from mechanical inertia and resonance. For AC drives, Pulse Width Modulated (PWM) technology is the primary industry standard. AC Drives or Variable Frequency Drives Classification by Size. ; ARC has segmented the AC drives market into five size ranges as defined by the drives’ output kilowatt and horsepower ratings. While ARC’s low power AC drives global market research study includes micro, low-end, and midrange drives, ARC’s high power AC drives global market research study includes the midrange, high-end, and mega drives markets. ARC has included midrange AC drives in both the low power and high power market studies. Many AC drives models have a very wide operating power range. For example, some suppliers offer a variation of the same model of AC drives that operates from low to high power ranges. Suppliers may offer a range of products that fall into multiple segmentations. Since such models can span different kilowatt segmentations, ARC has allocated the sales of these drives into their single most appropriate segmentation to avoid double counting. When AC drives are mounted on motors, this study only accounts for the drives portion, based on its appropriate AC drives type. Micro Drives Micro drives are the smallest units, controlling motors from a fraction of a kilowatt up to five kilowatts. Many micro drives models are basic and very similar to low-end drives models in technology and configurations. However, some suppliers offer micro drives that are simply lower power range versions of higher power range models, possessing many of the advanced features and functions of their higher-powered counterparts. Largely a commodity market, micro drives are used in various industrial and commercial machinery applications. Micro drives are usually sold through distributors or directly to large OEMs. Manufacturers of micro drives vary from small suppliers with drives as their sole products, to multinational conglomerates with a myriad of products. Most AC drives suppliers provide micro drives products. Low-End Drives Low-end drives control motors of 5 to 40 kilowatts. Many low-end drives models are basic and very similar to micro drives models in technology and configurations. Again, some suppliers offer low-end drives that are simply lower power range versions of higher power range models possessing many of the advanced features ...

When the Shenzhen V&T Technologies Co.,Ltd. inverter runs in vector control mode, it is highly dependent on accurate motor parameters, which is one of the important differences with V/F control mode.To ensure good driving performance and operating efficiency of the frequency inverter, the accurate parameters of the controlled motor can be obtained by three methods: static self-tuning (P9.15=1), rotary self-tuning (P9.15=2) and known parameters of the motor is input by hand . The first step: completely detach the motor from the load (it is recommended to detach the load) under the condition of complete power failure of the equipment, so that the motor can rotate freely without load. The second step: after power on, restore all parameters of the frequency inverter to the factory set value (this step is not required). The third step: "P0.12 maximum output voltage (motor rated voltage), P0.15 basic operating frequency (motor rated frequency), P9.01 motor pole number, P9.02 motor rated speed, P9.03 motor rated power and P9.04 motor rated current" are the basic parameters of the motor, which must be set correctly according to the actual parameters of the nameplate of the controlled motor. The fourth step: self-tuning on start parameters, please ensure that the motor is in a static state. P9.15=2 select the self-setting mode of rotation parameters and press the RUN key on the operation panel to display "-At-". At this time, the frequency inverter will drive the motor acceleration and deceleration operation, operators should pay attention to safety, tuning operation about 1 minute. After dynamic tuning, the frequency inverter will automatically calculate the key parameters of the motor (P9.05 ~ P9.14). Notes: 1.If there is a over-current and over-voltage fault in the self-setting process, the acceleration and deceleration time P0.08 and P0.09 can be appropriately extended. 2.If the frequency inverter and motor power do not match, please select static self-setting. After setting, it is necessary to manually change the no-load current P9.05 to about 40% of the rated current P9.04 in motor. 3.The value of magnetic saturation coefficient in P9.10 ~ P9.14 is automatically set in the self-setting time without user setting. 4.Static parameters are self-tuning. Press the "run" button to automatically measure motor parameters P9.06 ~ P9.08. 5.Key motor parameters that affect the operation control of the inverter are determined by performing self-tuning on parameters. These motor parameters will be automatically saved in the inverter after completing the self-tuning process until the next input parameter or self-tuning on parameter again. 6.If the motor can be off the load, it can choose to self-tuning on rotate, otherwise only static self-tuning.

When Nikola Tesla developed and patented the AC induction motor in 1924 (as well as the syncronous and split phasemotors) it had the endearing characteristic that it can be run by direct connection to a three phase power source. The motor speed is directly proportional to the applied frequency and is determined by the formula n = 120f/p where n is the synchronous speed of the motor in rpm, f is the frequency of power applied and p is the number of poles on the rotor. Therefore a 2 pole induction motor running at 60 Hz will run at 3600 rpm synchronous speed less the slip required to produce the induction effect at full load. This slip is variable depending on the motor design but for the “standard” NEMA design B motor it is 3 to 5 % making the typical 2 pole motor run at 3500 rpm at full load at 60 Hz. Soon after the AC motor was developed, the idea of varying the speed was considered and the only practical way of doing this at the time was to provide the motor with a variable frequency obtained by using a DC motor turning an AC alternator which allowed a variable frequency. This was done on a wide range of applications in the 50s, 60s, and 70s. Since the much simpler Ward-Leonard system existed for DC motors, however the major use for such lines was in precision controlled multimotor lines where synchronous AC motors were used for each section and when the master alternator frequency was varied, all the motors would follow together with synchronous accuracy. Such systems were still being installed on new machines as late as the mid 80s when static variable frequency controls became widely used. Static AC variable speed drives that were readily available were of the six step, variable voltage design. Later, when Phillips/Signetics came out with a sine coded PWM chip set, sine coded PWM drives became the norm and six step variable frequency faded into non-use except for unusual applications where the slightly lower loss at full speed, full load was an advantage. An induction or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is induced by electromagnetic induction from the magnetic field of the stator winding. An induction motor therefore does not require mechanical commutation, separate-excitation or self-excitation for all or part of the energy transferred from stator to rotor, as in universal, DC and large synchronous motors. An induction motor’s rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used in industrial drives because they are rugged, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFDs) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective i...
When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, AC motor speed control requires either varying the magnetic flux or changing the number of poles on the motor. Even decades after the induction motor gained widespread use, changing the frequency for speed control remained an extremely difficult task — and the physical construction of the motor prevented manufacturers from creating motors with more than two speeds. As a result, DC motors were necessary where accurate speed control and significant power output were required. In contrast to AC motor speed control requirements, DC motor speed control was achieved by inserting a rheostat into the low-power DC field circuit, which was feasible with available technology. These simple motor controls varied the speed and torque, and were the most economical way to do so for a number of decades. By the 1980s, AC motor drive technology became reliable and inexpensive enough to compete with traditional DC motor control. These variable frequency drives (VFDs) accurately control the speed of standard AC induction or synchronous motors. With VFDs, speed control with full torque is achieved from 0 rpm through the maximum rated speed and, if required, above the rated speed at reduced torque. VFDs manipulate the frequency of their output by rectifying an incoming AC current into DC, and then using voltage pulse-width modulation to recreate an AC current and voltage output waveform. However, this frequency conversion process causes 2% to 3% loss as heat in the VFD — caloric energy that must be dissipated. The process also yields over-voltage spikes and harmonic current distortions. Variable-frequency types There are three common types of VFDs. Current source inversion (CSI) has been successfully used in signal processing and industrial power applications. CSI VFDs are the only type that has regenerative power capability. In other words, they can absorb power flow back from the motor into the power supply. CSI VFDs give a very clean current waveform but require large, expensive inductors in their construction and cause cogging (pulsating movement during rotation) below 6 Hz. Voltage source inversion (VSI) drives have poor power factor, can cause motor cogging below 6 Hz, and are non-regenerative. Consequently, CSI and VSI drives have not been widely used. Pulse-width modulation (PWM) VFDs are most commonly used in industry because of excellent input power factor due to fixed DC bus voltage, no motor cogging, higher efficiencies, and lower cost. A PWM VFD uses a series of voltage pulses of different lengths to simulate a sinusoidal wave (Fig. 1 on page 8). Ideally, the pulses are timed so that the time average integral of the drive yields a perfect sinusoid. The current method of choice to produce this waveform runs a triangle wave and sine wave through a comparator, and...
