Abstract
To effectively cover a coil end with a resin layer. A method for manufacturing a stator includes a first resin layer forming step (ii) of forming a first thermoset resin layer by impregnating the tip end side of a coil end with first thermoset resin, the coil end protruding from the core of the stator, the first thermoset resin having liquidity; a second resin layer forming step (iii) of forming a second thermoset resin layer on the first thermoset resin layer by dropping second thermoset resin from the core side of the coil end toward the tip end side; and a curing step of curing the first thermoset resin and the second thermoset resin.
Claims16
A method for manufacturing a stator, comprising:
- a first resin layer forming step of forming a first thermoset resin layer by impregnating a tip end side of a coil end with first thermoset resin, the coil end protruding from a core of the stator, the first thermoset resin having liquidity;
- and
- a second resin layer forming step of forming a second thermoset resin layer on the first thermoset resin layer by dropping second thermoset resin from a core side of the coil end toward the tip end side;
- and
- a curing step of curing the first thermoset resin and the second thermoset resin.
A stator comprising:
- a first resin layer covering a tip end portion of a coil end protruding from a core of the stator;
- and
- a second resin layer laminated on a core side of the first resin layer so as to cover a surface of the first resin layer on the core side.
