Abstract:
A motor control system for induction-type AC electric motors having starting and run windings has a multiphase VFD drive with first and second phase outputs. A switching device with a first position, where a first output of the VFD drive is coupled to the run winding and a second output of the VFD drive couples to the start winding; and with the switching apparatus in second position, the run winding of the AC electric motor couples to an AC line input and the start winding of the AC electric motor couples through a capacitor and start switch to the AC line input. With the switching device in the first position, the second output of the VFD is configured to discontinue driving the start winding of the motor after the motor begins rotating.
