What is an AC Variable Frequency Drive? 

The most common use of Variable Frequency Drives (VFDs) is for the control of motors, pumps, fans, and compressors. Motor drives are referred to by many names: variable speed drive, adjustable speed drive, AFD, frequency drive, inverter, AC Drive, motor drive, vector drive, and others. They all control motor speed and/or torque by varying the frequency and voltage of the power supply to the electric motor.  Our systems engineering department brief you on how a VFD works, the expected life of a VFD, how to control your motor speed with a VFD, how to control motor torque with a VFD, and the way to calculate the energy costs savings of using a VFD

Using VFDs has proven to save energy and optimizes the operation and wear on motors and other applications relying on electric motors. Motors are stressed when they required to be “turned on” full speed and stopped suddenly. Think about your air conditioner unit at your house; it starts at full speed and many times the lights in your house may dim from the sudden inflow of electricity to start the compressor at full speed. A VFD has the capacity to ramp-up or down a motor during a start or a stop, decreasing the mechanical stress on the motor and avoiding spikes of electricity use.
