An AC drive is an electronic device that is used to adjust the rotating speed or torque of a standard, electric AC motor. The electric motor, in turn, drives a load such as a fan, pump or conveyor. AC drives are also referred to as frequency converters, variable frequency drives (VFD), variable speed drives (VSD), adjustable frequency drives (AFD), adjustable speed drives (ASD) or inverters.
