Abstract

The present invention provides a stator of an outer rotor motor for a washing machine. The stator includes a ring type helical core, an upper insulator having a shape corresponding to a shape of the helical core to enclose an upper part of the helical core, a lower insulator having a shape corresponding to the shape of the helical core to enclose a lower part of the helical core, 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, a locking hole provided to the locking part to fix the stator to the fixing side of the tub via a locking member, and a rigidity reinforcement bracket provided between the upper and lower insulators.
