Stator coil production method including in-slot portion shaping step and coil-end portion shaping step
Abstract:
A stator coil producing method and a stator coil production machine. The stator coil is used in an electric rotating machine. The stator coil production machine includes a rotary retainer which rotates to move shaping press pairs along a looped path. The rotary retainer has retaining holes through which the shaping press pairs are retained. The retaining holes are shaped to permit the shaping press pairs to move along the looped path, thereby pressing or shaping portions of a conductor wire into in-slot portions to be disposed in slots of a stator core and coil-end portions each of which is to extend between adjacent two of the in-slot portions outside the slots. The method comprises an in-slot portion shaping step of shaping portions of the insulator-coated conductor wire into the in-slot portions and a coil-end portion shaping step of shaping portions of the insulator-coated conductor wire into the coil-end portions.
