Motor for a washing machine including a driving shaft coupled to a drum of the washing machine, a stator for forming a magnetic field by means of a coil wound on a core, and a rotor rotatably mounted on an outside of the stator coupled to the driving shaft for driving the driving shaft, wherein the rotor includes a rotor frame of metal having magnets attached to an inside surface of an outer end, 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 at a center of the rotor frame having one end portion of the driving shaft secured thereto, a bushing of a non-conductive resin having the shaft supporting housing formed as one body at a center, the bushing being secured to the rotor frame, and fastening members for fastening the bushing to the rotor frame, thereby enhancing security of operation, and, because a complicated injection molding can be eliminated by application of rotor frame of metal, reducing a time period required for fabrication and improving production yield. <IMAGE> |
