Patent ID: 7271512

Claim:
A stator of an outer rotor type motor for a drum type washer, comprising: a ring type helical core having a multi-layer structure configured by helically winding to stack a steel plate, which comprises a strap type base and teeth protruding from the base, from a bottom layer to a top layer; an upper insulator having a shape corresponding to a shape of the helical core to enclose an upper part of the helical core and formed of an electrically insulating material; a lower insulator having a shape corresponding to the shape of the helical core to enclose a lower part of the helical core in being assembled to the upper insulator reciprocally and formed of the electrically insulating material; at least one locking part built in one body of the upper and lower insulators and projected from an inside of the helical core toward a center of the stator to fix the stator to a fixing side of a tub; and a rigidity reinforcement bracket provided between the upper and lower insulators.
