Abstract:
1. A dynamoelectric stator comprising: a cylindrical stator core in which a large number of slots are arranged at a predetermined pitch circumferentially so as to be open on an inner peripheral side; and a stator winding having a plurality of phase windings installed inside said slots, said plurality of phase windings forming first and second coil end groups at first and second axial end portions of said stator core, wherein: phase winding lead portions are each led out from said first coil end group so as to constitute a led out portion, subsequently led around circumferentially along an apex portion of said first coil end group so as to be separated from said apex portion, and joined to a respective joined phase winding lead portion to constitute said stator winding; and at least one of said phase winding lead portions constitutes a fastened lead portion fixed to an unjoined phase winding lead portion lying parallel circumferentially along said apex portion of said first coil end group by fastening using a fastening member.
