Rotary electric machine

Abstract

To provide a rotary electric machine which can improve cooling performance of stator cooling by coolant.SOLUTION: A plurality of electromagnetic steel sheets 200A comprises: a plurality of fastening parts 201a to 201c; and a plurality of circular arc-shaped outer peripheral parts provided between other fastening part adjacent to the fastening parts, at least one of the plurality of circular arc-shaped outer peripheral parts forms a small diameter part 206a having a radius R0, the other forms a large diameter part 206b having a radius R2 larger than the radius R0, a communication part 203 and a slit 204 are formed in a pair of fastening parts 201a, 201b adjacent to each other on both sides of the small diameter part 206a and laminated so that the small diameter part 206a faces the large diameter part 206b of the adjacent electromagnetic steel sheet 200A, and the communication part 203 faces the communication part 203 of the adjacent electromagnetic steel plate 200A.SELECTED DRAWING: Figure 2
