Abstract
A coil for a rotary electric machine is mounted in a plurality of slots of a stator core having the slots in a circumferential direction. An overlapping coil-type wave winding coil constituted by a coil wire having a plurality of slot accommodating portions accommodated in the slots and a plurality of coil end portions interconnecting, in a chevron shape, the slot accommodating portions next to each other outside the slots in an axial direction of the stator core constitutes the coil. At least two layers of the coil wire are connected by a continuous wire-based connecting portion, folded back in the connecting portion, and stacked.
Claims7
A coil for a rotary electric machine mounted in a plurality of slots of a stator core having the slots in a circumferential direction, the coil comprising:
- a plurality of sequentially stacked coil wires, wherein each of the coil wires defines an overlapping coil-type wave winding coil constituted by the coil wire having a plurality of slot accommodating portions accommodated in the slots and a plurality of coil end portions interconnecting the slot accommodating portions next to each other outside the slots in an axial direction of the stator core;
- and
- a continuous wire-based connecting, portion that connects at least two layers of the sequentially stacked coil wires,
- wherein the plurality of the coil wires are sequentially stacked such that a stacking order of the plurality of the coil wires between the at least two layers next to each other is reversed and the plurality of the coil wires are folded back with the stacking order maintained in the connecting portion.
