Abstract
This production method produces a stator that includes a plurality of segment coils that are annularly arranged in a plurality of layers that overlap in the radial direction of a stator core. The production method involves a tool that has teeth being moved by a robot manipulator and the teeth being inserted between the ends of leg parts of the layers. The ends that engage the teeth are thereby bent so as to be substantially crank-shaped. Before the teeth are inserted between the ends, a restraining jig is inserted between bend parts of the segment coils of the layers and an end surface of the stator core that is on one side in the axial direction.
