Abstract

PURPOSE:To obtain a stator, characterized by a small amount of resin application, and having no poor insulation and wire breakage, by making the molding size of the coil end part having a lead connector of a stator winding layer larger than the size of the coil end part on the other side. CONSTITUTION:In the case the coil end is formed after the stator winding is inserted in a stator core, the size phid2 of the outer diameter of the coil end part on the side having the lead connector of the winding is larger than the size phid1 of the diameter of the coil end part on the opposite side. Furthermore, the size phiD2 of the inner diameter of the upper mold 8 is larger than the size of phiD1 of the lower mold 7 so as to provide the relatively same clearance. The mold size for the coil end part on the side having the lead connector is larger. In this constitution, the thickness of the resin on both coil ends can be thinned, and the wire breakage due to the biting of the metal molds does not occur.
