Abstract
This method for manufacturing a coil includes a cross section forming step for transforming an outer shape of a part to be housed in a slot in a coil wire that has a circular cross section and is not subjected to an insulation coating process, and an insulation step for performing, after the cross section forming step, the insulation coating process on the coil wire after cross section forming.
Claims11
A method for manufacturing a coil to be disposed in a stator including slots, the method comprising:
- a bending step for bending a coil wire that is not subjected to an insulation coating process so that the coil wire is disposed in the stator;
- a cross section forming step for transforming an outer shape of a part to be housed in the slot in the coil wire that has a circular cross section and is not subjected to the insulation coating process;
- and
- an insulation step for performing, after the bending step and the cross section forming step, the insulation coating process on the coil wire after bending and cross section forming.
A method for manufacturing a stator including a stator core including slots and a coil disposed in the stator, the method comprising:
- a bending step for bending a coil wire that is not subjected to an insulation coating process so that the coil wire is disposed in the stator core;
- a cross section forming step for transforming an outer shape of a part to be housed in the slot in the coil wire that has a circular cross section and is not subjected to the insulation coating process;
- an insulation step for performing, after the bending step and the cross section forming step, the insulation coating process on the coil wire after bending and cross section forming;
- and
- a coil disposing step for disposing, after the insulation step, in the stator core, the coil formed from the coil wire after the bending, the cross section forming, and the insulation coating process.
