Manufacturing jig for stator
First Claim
1. A method of manufacturing a stator, the stator comprising:
- a substantially annular stator core which is formed by stacking, in layers, a plurality of thin plates where a plurality of fastening holes are formed in a vicinity of a circumferential edge portion such that the fastening holes are aligned in a stacking direction; and
electrical conductors which are partially inserted into a plurality of slots formed in the stator core,wherein the method of manufacturing the stator comprises;
an attachment step of attaching, to the stator core when a powder resin is applied to the electrical conductors, a plurality of holding members, each of the plurality of holding members being a different body from other of the plurality of holding members, the plurality of holding members being arranged separately from one another in a circumferential direction of the stator core, and the plurality of holding members respectively covering the fastening holes and a vicinity thereof from above in the stacking direction of the thin plates, and the plurality of holding members each have a hole which communicates with a respective fastening hole of the stator core following attachment of the plurality of holding members to the stator core, thus forming a corresponding pair comprising one fastening hole and one hole, the plurality of holding members attaching to the stator core by fastening by inserting a fastening member into each corresponding pair;
a heating step of heating the stator core by induction heating;
a coating step of coating the electrical conductors heated in the heating step with a resin; and
a removal step of removing the plurality of holding members from the stator core after the coating step.

Abstract
A manufacturing jig for a stator, the stator including a substantially annular stator core and electrical conductors. The stator core is formed by stacking, in layers, a plurality of thin plates where a plurality of fastening holes are formed in a vicinity of a circumferential edge portion so that the fastening holes are aligned in the stacking direction. The electrical conductors are partially inserted into a plurality of slots formed in the stator core. The manufacturing jig is attached to the stator core when a powder resin is applied to the electrical conductors and includes hole portions. The hole portions are arranged being divided in a circumferential by being divided in a circumferential direction of the stator core, cover the fastening holes and a vicinity thereof from above, and are formed so as to be able to be fastened to the fastening holes of the stator core.
