<p>Stator structure (6) of an outer rotor type motor for a drum type washing machine including an annular core (HC) of a multi-layered structure formed by stacking a steel plate having a belt shaped base (150) and T (151) projected from the base while winding the steel plate in a helix starting from a bottom layer to a top layer, and upper (60a), and lower (60b) insulators of an electric insulating material covered on upper, and lower sides of the helical core in shapes complementary to a shape of the helical core, wherein each of the upper insulator and the lower insulator includes three or more than three fastening portions (600) formed as one body therewith projected from an inner side of the helical core toward a center of the stator for fastening the stator to a fixing side of the tub, the fastening portion has a fastening hole (620a) for fastening the stator to a fixing side of the tub with a fastening member, and each of the bosses of the upper, and lower insulators includes a raised portion (621) projected from a side facing the other insulator toward an opposite insulator.</p> |
