Definition: An AC drive is a motor speed controller for three-phase AC motors. It controls the speed of the electric motor by varying the frequency of the voltage supplied to the motor. The motor current is controlled by varying the magnitude of the applied voltage.

Benefits: A VFD allows users the opportunity to match the speed of the motor to the load that is required. Use of a VFD can increase production, tighten process control, extend equipment life, reduce maintenance costs, and optimize your motor speed control processes.

Typical application types can include but are not limited to: Fans, Blowers, Pumps, Mixers, Conveyors, Compressors, Stamping/Punch Presses, Dynamometers, and Extruders.

The term AC drive could also be known as: VFD, variable frequency drive, variable speed drive, adjustable speed drive, adjustable frequency drive, AC inverter, and motor speed controller.
