Abstract
A dual voltage motor drive is disclosed. In an exemplary embodiment, the motor includes a rotor assembly, rotatingly disposed within a stator assembly, and a plurality of motor phase windings configured to be energized in a determined sequence to cause a rotation of the rotor assembly. The plurality of motor phase windings are divided into a first group of windings selectively energized by a first voltage source, and a second group of windings selectively energized by a second voltage source, wherein the motor remains operational in the event of a failure of one of the first and second voltage sources.
