Document Type and Number:
WIPO Patent Application WO/2020/162290
Kind Code:
A1
Abstract:
According to the present invention, a stator winding (721) has a plurality of phase windings (723) provided for each phase. In the stator winding, an inter-wire member is not provided between coil-side wire parts (724) circumferentially arranged side by side. The phase winding of each phase has a predetermined number of coil-side wire parts for each magnetic pole, and at a first coil end (CE1) on one axial end, the same phase coil-side wire parts are connected by two magnetic poles circumferentially adjacent to each other via a first bridging part (751). In addition, at a second coil end (CE2) on the other axial end, the same phase coil-side wire parts are connected by two magnetic poles, which are circumferentially separated while sandwiching the two magnetic poles via a second bridging part (752) that circumferentially extends in the same direction as the first bridging part.
