Abstract

PURPOSE:To eliminate the protruding part of a returning part by inserting a film along the planar shape of the slot of a stator core, and providing notched parts having the same size of the returning width at four places of both ends of the returning part of a slot insulating film that is engaged with the edge of the stator core at a cuffs-shaped returning part provided at both end parts in the inserting direction. CONSTITUTION:A cuffs-shaped returning part 9a, which is formed by bending in the anti-slot direction along a returning line 9b, is formed at both ends of a slot insulating film 9 in the inserting direction into a slot 11. Notched parts 9c having the same size as a returning width (h), are formed at both end parts of the returning part 9a. The slot insulating film 9, which is bent and molded in the approximately same shape as the planar shape of the slot 11, is inserted into a plurality of slots 11 of a laminated stator iron core 4. A required amount of windings are wound in series from a slot opening part 11a. Even if the returning part spreads in the anti-slot direction, the end part does not protrude on the outer surface of the stator core, and abnormal sound is not generated.
