description A laminated body of a motor includes: a yoke spirally laminated to form a hollow cylindrical shape; a plurality of teeth protruding from one side edge of the yoke disposed along a longitudinal direction of the yoke and being separated apart at a predetermined distance; a plurality of notch portions on an opposite side edge of the yoke, each of the plurality of notch portions being aligned with each of the plurality of teeth; a stopping protrusion extendingly formed at a protruding end of the teeth in the longitudinal direction of the yoke; and an inclined portion having an inclined surface formed by decreasing a width of the stopping protrusion toward an end of the stopping protrusion so as to reduce cogging torque.
