  • AC Motors, Controllers, and Variable Frequency Drives

    A Variable Frequency Drive operates differently; it eliminates excessive current, increasing voltage and frequency in a controlled manner as the motor starts. This allows the AC motor to generate up to 150% of its rated torque, which could potentially be generated from the beginning, all the way up to full speed, without wasting energy.

  • What is a Variable Frequency Drive?

    2014-3-20u2002·u2002A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.. Frequency (or hertz) is directly related to the motor's speed (RPMs).
