Patent ID: 8427024

Claim:
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, wherein each 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, and the 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.
