Stator in small electric machine

摘要

A stator in a small electric machine such as a micromotor comprises: a stator core provided with tooth-like poles and fully opened winding accommodating slots; and a special sleeve provided with protruded portions and bridging portions connecting the protruded portions, the special sleeve being inserted in the stator core in such a manner that the protruded portions contact the ends of the tooth-like poles of the stator core thereby closing the winding accommodating slots. The stator thus organized facilitates the insertion of the windings into the winding accommodating slots.
