Abstract

A stator includes: a stator core, the stator core including a plurality of slots arranged in a circumferential direction of the stator core and recessed in a radial direction of the stator core; a coil disposed in each of the slots; an insulating heat-dissipating member disposed between the stator core and the coil on one of two side surfaces of the slot in the circumferential direction of the stator core; and an insulating foaming member disposed between the stator core and the coil on the other of the two side surfaces of the slot in the circumferential direction of the stator core.

Claims (12)

1. A stator comprising:

a stator core, the stator core including a plurality of slots arranged in a circumferential direction of the stator core and recessed in a radial direction of the stator core;

a coil disposed in each of the slots;

an insulating heat-dissipating member disposed between the stator core and the coil on one of two side surfaces of the slots in the circumferential direction of the stator core; and

an insulating foaming member disposed between the stator core and the coil on the other of the two side surfaces of the slot in the circumferential direction of the stator core.

2. The stator according to claim 1 , wherein:

the insulating heat-dissipating member is a member having a heat-dissipating material bonded to an insulating sheet; and
