Title:
STATOR OF ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/012554
Kind Code:
A1
Abstract:
In a stator (13) of a rotary machine, parallel windings (U1, U2, V1, V2, W1, W2) of each phase among individual phase windings are connected in parallel, and the parallel windings of each phase each include, from among a plurality of partial windings that constitute the parallel windings, a power wire partial winding (C1) that is connected to a power supply side, a neutral wire partial winding (C2) that is connected to a neutral point, and a 5-pitch cross-over wire (61, 63) and/or a 7-pitch cross-over wire (62) that are disposed in the middle between the power wire partial winding and the neutral wire partial winding. A 5-pitch cross-over wire and a 7-pitch cross-over wire of two phases out of the three phases are disposed so as to overlap in an axial direction, two 5-pitch cross-over wires of the one remaining phase are disposed so as to be separated from each other in a circumferential direction. The power wire partial windings are disposed such that power wire partial windings of the same phase are adjacent to each other or are adjacent to a neutral wire partial winding of a different phase.
