Stator
First Claim
1. A stator comprising:
- a stator core including teeth and slots formed between the teeth; and
coils each being made of a flat rectangular conductor and placed in the slots, whereineach coil has a shape including, in a coil end portion, oblique side portions and a protrusion formed to protrude upward in an axial direction of the stator core from the oblique side portions,the protrusion has a height to avoid interference between the coils placed in the stator core, andthe coil end portion of each coil is formed with a lane-change portion,a coil interference-point distance between a first interference point at which a first coil and a second coil arranged adjacently interfere with each other and a second interference point at which the second coil and a third coil arranged adjacently interfere with each other is determined to be equal to or shorter than a bending center-to-center distance defined as a distance in a circumferential direction of the stator core between a bending center on an inner circumferential side of the lane-change portion located on the inner circumferential side of the stator core and a bending center on an outer circumferential side of the lane-change portion located on the outer circumferential side of the stator core.

Abstract
To provide a stator capable of achieving downsizing and high output power and a stator manufacturing method, a stator comprises a split stator core and slots formed between the teeth, and protrusion-formed coils each being made of a flat rectangular conductor and placed in the slots. Each protrusion-formed coil has a shape including, in a coil end portion, a lead-side protrusion or a non-lead-side protrusion formed to protrude upward in an axial direction of the stator core from a first oblique side portion, a second oblique side portion, a third oblique side portion, and a fourth oblique side portion, and a first oblique side portion, a second oblique side portion, a third oblique side portion, and a fourth oblique side portion. The lead-side protrusion or the non-lead-side protrusion is designed with a height to avoid interference between the protrusion-formed coils placed in the stator core.
