US Patent 10505424 Stator of rotating electric machine

Each of phase windings includes parallel windings for each phase connected together in parallel, and the parallel windings include power-wire partial windings connected to a power supply side, neutral-line partial windings connected to a neutral point, and at least one of a set of 5-pitch and 7-pitch jumper wires, the power-wire partial windings, the neutral-wire partial windings, and the jumper wires being included in the plurality of partial windings forming the parallel windings. For two of the three phases, each of the 5-pitch jumper wires and a corresponding one of the 7-pitch jumper wires overlap each other, and for the remaining single phase, two of the 5-pitch jumper wires are spaced from each other in the circumferential direction, and each of the power-wire partial windings is adjacent to another power-wire partial winding for an identical phase or to a corresponding one of the neutral-line partial windings for a different phase.
