METHOD OF MANUFACTURING MOLDED STATOR OF DYNAMO ELECTRIC MACHINE

摘要

A method of manufacturing the molded stator of a dynamo electric machine comprises a lamination step for constituting a split lamination core group structure (7) by laminating a plurality of core sheets (6) in each of which a plurality of core pieces (61) are bonded to one coupling part through a bridge (62), a winding step for winding a coil around the tooth of each split lamination core (71) of the split lamination core group structure (7), a cutting step for cutting the split lamination core (71), around which a coil is wound, at the bridge and separating the split lamination core, a temporary fixing step for shaping a plurality of split lamination cores (71) into an annular stator (2) and fixing the stator temporarily, and a molding step for setting the stator (2) in a die by inserting a mold mandrel (10) to the inner circumferential side of the stator, and fixing the outer circumferential surface of the stator (2) with resin.
