Title:
STATOR AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/024606
Kind Code:
A1
Abstract:
This stator includes a stator core (13) having a plurality of teeth (16) that are provided in a circumferential direction, and coils (U1 to U6, V1 to V6, W1 to W6, U11 to U14, V11 to V14, and W11 to W14) which are wound in a concentrated manner onto each of the plurality of teeth. Each coil comprises an electric wire having an insulating coating (14a) on the surface thereof. The stator generates a rotating magnetic field on the basis of the supply of a three-phase alternating current to the coils. No insulation member other than the insulating coating is interposed between coils that are adjacent to one another in the circumferential direction and that are in phase with one another. An insulating member (50) that is separate from the insulating coating is interposed between coils that are adjacent to one another in the circumferential direction and that are out of phase with one another.
