Abstract:

In order to electrically insulate a stator core (16) of an electric motor and a winding (22) disposed in a slot (20) formed in the core (16), an insulating member (10) disposed in the slot (20) includes a main insulating portion (30) for covering the inner wall surface of the slot (20) and an insulation assisting portion (32) having desired flexibility and bending repulsiveness for substantially closing an opening (26) in the slot. The insulation assisting portion (32) is easily deformed when an external force is applied thereto so as to partially open the opening (26), while when the external force is removed, it is restored to its original state in which the opening (26) is closed.
