Abstract

Official abstract text for this publication.

A stator of a rotating electric machine includes plural slots disposed in a circumferential direction of a stator core, and a coil body formed by a coil that is disposed as a single conductor in the slot in the circumferential direction of a stator core and that is wound for plural turns in the slot in a radial direction of a stator core. The coil has a flat conductor section, a magnetic body layer provided around the flat conductor section, and an insulating film provided around the magnetic body layer.

First claim

Opening claim text (preview).

What is claimed is: 1. A stator for a rotating electric machine, the stator comprising: a stator core having plural slots disposed in a circumferential direction of the stator core, the plural slots including a first slot; and a coil body located in the first slot and configured with a plurality of coils arranged in a single row along a radial direction of the stator core, each of the plurality of coils being wound for only one turn, wherein the plurality of coils includes first coils and second coils, and the first coils and the second coils are alternately disposed along the radial direction, each first coil is configured with a first flat conductor section, a first magnetic body layer provided around the first flat conductor section and a first insulating film provided around the first magnetic body layer, and each second coil is configured with a second flat conductor section and a second insulating film provided around and in direct contact with the second flat conductor section. 2. The stator according to claim 1 , wherein the plurality of coils includes an innermost coil disposed on an innermost peripheral side of the first slot in the radial direction of the stator core, the innermost coil being a first coil. 3. The stator according to claim 1 , wherein a magnetic permeability of the first magnetic body layer is hundreds of times higher than a magnetic permeability of the first flat conductor section.
