Abstract
A stator according to an embodiment includes: an annular stator core having a plurality of teeth arranged in a circumferential direction and protruding radially inward, and a plurality of slots formed between the teeth in the circumferential direction; a coil disposed in the slot; and an insulating member including resin or rubber, surrounding the coil in the slot and fitted into the slot in a press-fitted state. A groove is formed in a facing surface of the insulating member, the facing surface facing a wall surface of the slot, and a space surrounded by an inner surface of the groove and the wall surface of the slot is a refrigerant flow path.
Claims8
A stator comprising:
- an annular stator core that has a plurality of teeth that are arranged in a circumferential direction and protrude radially inward, and a plurality of slots that are formed between the plurality of teeth in the circumferential direction;
- a coil that is disposed in each of the plurality of slots;
- and
- an insulating member that includes resin or rubber, surrounds the coil in the each of the plurality of slots, and is fitted into the each of the plurality of slots in a press-fitted state,
- wherein a groove is formed in a facing surface of the insulating member, the facing surface facing a wall surface of the each of the plurality of slots, and
- a space surrounded by an inner surface of the groove and the wall surface of the each of the plurality of slots is a refrigerant flow path.
A method of manufacturing a stator comprising:
- a molding step of molding an insulating member that includes resin or rubber and surrounds a coil to integrate the coil and the insulating member;
- a flow path forming step of providing a refrigerant flow path in the insulating member;
- and
- an inserting step of inserting the insulating member in which the refrigerant flow path is provided and the coil into each of a plurality of slots of an annular stator core having a plurality of teeth that are arranged in a circumferential direction and protrude radially inward and the plurality of slots that are formed between the plurality of teeth in the circumferential direction.
