  • 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...

  • Can I put a VFD on any motor?
    • August 30. 2021

    When a variable frequency drive (VFD) is added to an existing system, many potential problems may arise. Reduced cooling at reduced speed Most motors running across the line depend on an internal, shaft-driven fan for cooling. When the motor is operated with a VFD, the motor shaft speed (motor speed) decreases and will cause decreased cooling from the shaft-driven fan. If the load is a standard va...

  • What is the difference between a soft starter and a VFD (variable frequency drive) for electric motors?
    • September 03. 2021

    The major difference between soft starter and VFD are as follows. 1. Soft starter is used to start and stop the motor smoothly., without jerk load. 2. The starting torque delivering capacity of the soft starter is poor as V/f ratio or the flux is much lower than the rated capacity of the motor flux. It is suitable for the driven equipment which start at almost no load. 3. VFD is also soft start an...
