Patent ID: 7397158

Claim:
A motor for a washing machine, comprising a driving shaft coupled to a drum of the washing machine, a stator for forming a magnetic field with a coil wound on a core, and a rotor rotatably mounted on an outside of the stator, the rotor being coupled to the driving shaft for driving the driving shaft, the rotor comprising: a rotor frame formed of metal having magnets attached to an inside surface of an outer end of the rotor frame; a back yoke on an outside surface of the outer end of the rotor frame for reinforcing the rotor frame and forming a magnetic path; a shaft supporting housing having a projection radiating from an outside circumferential surface of the shaft supporting housing, the shaft supporting housing at a center of the rotor frame and having one end portion of the driving shaft secured thereto; a bushing of a non-conductive resin being insert molded about the shaft supporting housing and engulfing at least the projection, where the shaft supporting housing is disposed at a center of the bushing thereby forming one body sharing contiguous surfaces at an interface of at least the projection and the bushing, the bushing being secured to the rotor frame; and fastening members for fastening the bushing to the rotor frame.
