Abstract
A stator of an electric motor provides pole retaining portions which retain the poles therein and are radially project at their end portions towards the outer periphery in a ring shape, whereby winding operations around the outer surface of the pole retaining portion are performed from the outside without any restriction, thus allowing a small-sized motor stator to be easily manufactured.
