Abstract
Official abstract text for this publication.
A coil including a first winding portion and a second winding portion arranged on a stator of a rotary electrical machine. The first winding portion is formed by edgewise-winding a conductive rectangular wire. The second winding portion is formed by edgewise-winding a conductive rectangular wire, which is connected to the first winding portion. Coil end parts of the first and second winding portions each include a crank-shaped section. The first and second winding portions are formed so that when slot insertion parts of the first and second windings are arranged in slots of the stator, a long side of a cross-section of the rectangular wire extends in the circumferential direction of the stator and a short side of the cross-section of the rectangular wire extends in a radial direction of the stator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coil arranged in a stator of a rotary electrical machine, wherein the stator includes a stator core having a plurality of slots arranged in a circumferential direction along an inner circumferential surface of the stator core, the coil comprising: a first winding portion formed by edgewise-winding a conductive rectangular wire, wherein the first winding portion includes two first slot insertion parts, which are respectively arranged in two first slot…
