  • AC Drives VFD Classifications
    • June 16. 2021

    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...

  • What’s the difference between AC and DC drives?
    • June 28. 2021

    When it comes to AC drives vs DC drives, DC drives are commonly considered problematic, despite their prestige for having simple circuits, providing high start-up torque, and being ideal for applications with constant speed due to the requirement of commutators and brush assemblies in their motors. These motors can become worn over time, have operational issues, and will likely require labor to pr...

    I.Why occur over current trip or over load trip in vector control 2 with encoder speed feedback? Check the parameter settings: (1)Check if the motor parameters are properly set (2)Check if the encoder pulse Pd.21 is properly set (3)Check if the encoder direction parameter of Pd.22 is properly set (4)Check if the ratio between motor and encoder Pd.24 is properly set Check the hardware connection (1...

  • how does a ac drive control speed
    • August 19. 2021

    The ac drive controls the speed of the pump and fan by changing the electrical energy supplied rather than damping the air- or water flow. It is like reducing the speed of a car by pressing less on the accelerator instead of using the brake to slow down the speed. The payback time of an ac drive is typically one year or less. Other benefits of using ac drive to control the speed of fan or pump are...

  • What are the applications of AC drive?
    • August 24. 2021

    Drives are widely used in manufacturing industries to regulate and control rotating equipment such as fans, conveyors, machine spindles, and pumps, which are used in production processes. AC drives are widely used in process industries to increase the efficiency of equipment. It controls the speed of electric motors according to the process needs, typically reduces energy consumption by 35-40%. Ho...

  • Variable Frequency Drive VS Variable Speed Drive
    • August 26. 2021

    In modern industries, electric motors are playing a important role in modern technology. In an effort to decrease electric motor energy consumption in these energy-hungry devices―and optimize their efficiency―manufacturers have employed various drive-technologies to modify the motors' speed. These technologies, which include universal variable frequency drives (VFD, AC Drive Converter) and variabl...
