Dynamo-Electric Machine
First Claim
1. A stator of a dynamo-electric machine, comprising:
- a stator core with a plurality of slots formed in alignment in the circumferential direction; and
a stator coil with an insulating film inserted into the slots in the stator core,wherein the stator coil is composed of a first-layer segment to a fourth-layer segment each of which is formed by arranging a plurality of segment coils in the circumferential direction and which are arranged from the inner radius side to the outer radius side in the radial direction,wherein the first-layer segment and the second-layer segment are displaced from each other by a first amount of displacement in the circumferential direction and connected to each other, andwherein the third-layer segment and the fourth-layer segment are displaced from each other by a second amount of displacement different from the first amount of displacement in the circumferential direction and connected to each other.

Abstract
The heat dissipation of a coil of a stator is enhanced. A stator of a dynamo-electric machine or a dynamo-electric machine according to the present invention includes: a stator core in which a plurality of slots arranged in the circumferential direction are formed; and a stator coil with an insulating film inserted in the slots in the stator core. The stator coil is composed of a first-layer segment to a fourth-layer segment each of which is formed by arranging a plurality of segment coils in the circumferential direction and which are arranged from the inner radius side to the outer radius side in the radial direction. The first-layer segment and the second-layer segment are displaced from each other by a first amount of displacement in the circumferential direction and connected to each other. The third-layer segment and the fourth-layer segment are displaced from each other by a second amount of displacement different from the first amount of displacement in the circumferential direction and connected to each other.
