Abstract:
In a vehicle AC generator, a stator core (42) is formed by laminating thin steel sheets, the stator core (42) being provided with a plurality of slot portions (43) which accommodate a stator winding (41) and tooth portions (44) which define adjacent ones of the slot portions; the stator winding (41) is disposed in the slot portions to constitute a stator (4); the stator core (42) is filled with varnish (45) between laminates of each tooth (44) at least in an inner diameter end surface region which faces the rotor (3) and is coated with epoxy resin varnish (46) on the tooth surface of the inner diameter end surface region to form an anti-rust film.
