Abstract
A motor system includes a stator and a rotor situated to rotate relative to the stator. A plurality of phase windings are situated in the stator with a power circuit connected to the phase windings. A controller is configured to output control signals to the power circuit to selectively energize the phase windings to cause the rotor to rotate relative to the stator. A neutral switch circuit is connected between the phase windings and a neutral node and is configured to selectively disconnect the phase windings from the neutral node.
