Abstract
A stator of a rotary machine is provided with a first resin molded body, a second resin molded body and third resin molded bodies which electrically insulate a stator core and coils. The first resin molded body is attached to the stator core on a first side of a lamination direction in which steel sheets are laminated and the second resin molded body is attached to the stator core on a second side of the lamination direction. The third resin molded bodies have shapes extending along slot side surfaces and are contacting with a predetermined region of the slot side. First slot side portions of the first resin molded body overlaps end portions of a first side of the third resin molded bodies and second slot side portions of the second molded body overlaps end portions of a second side of the third resin molded bodies.
Claims4
A rotary machine, comprising:
- a rotor;
- and
- a stator, wherein
- the stator includes:
- a stator core which is formed by laminating steel sheets, and which includes a ring shaped yoke and a plurality of teeth protruding from the yoke to a side of the rotor;
- a plurality of coils which are provided to each of the plurality of teeth and are housed in a slot formed between adjacent teeth of the plurality of teeth;
- a first resin molded body which is attached to the stator core on a first side of a lamination direction in which the steel sheets are laminated, the first resin molded body electrically insulates the stator core and the coils;
- a second resin molded body which is attached to the stator core on a second side of the lamination direction, the second resin molded body electrically insulates the stator core and the coils, and
- a third resin molded body which has a shape extending along a slot side surface which forms the slot, the third resin molded body is provided in a state of contacting with a predetermined region of the slot side surface including a center portion of the stator core in the lamination direction, the third resin molded body electrically insulates the stator core and the coils, wherein
- the first resin molded body includes:
- a first end surface side portion covering a first end surface of the stator core which is the first side of the lamination direction;
- and
- a first slot side portion integrated with the first end surface side portion and is covering a first region of the first side of the lamination direction continuing to the first end surface, the first region is a portion in the lamination direction of the slot side surface, wherein the second resin molded body includes:
- a second end surface side portion covering a second end surface of the stator core which is the second side of the lamination direction;
- and
- a second slot side portion integrated with the second end surface side portion and is covering a second region of the second side of the lamination direction continuing to the second end surface, the second region is a portion in the lamination direction of the slot side surface
- wherein the first slot side portion overlaps with an end portion of the first side of the lamination direction of the third resin molded body,
- wherein the second slot side portion overlaps with an end portion of the second side of the lamination direction of the third resin molded body.
