DRIVE MOTOR FOR DRUM WASHING MACHINE, DRUM WASHING MACHINE HAVING SAME, AND DRIVE METHOD THEREOF

摘要

A drive motor includes: a double stator including a stator core, a first coil wound on one side of the stator core, and a second coil wound around the other side of the stator core; and a double rotor including a rotor support connected to a drum via a rotating shaft, an outer rotor fixed to the rotor support and arranged with a gap on the outer surface of the stator, and an inner rotor fixed to the rotor support and arranged with a gap on the inner surface of the stator. The drive motor drives to rotate two rotors of the double rotor by applying a drive power to the first and second coils at wash and rinsing strokes, and drives to rotate only one rotor of the double rotor by applying the drive power to only one of the first and second coils at a dehydration stroke.
