摘要

A coil production method capable of improving the space factor of a rectangular conductor with respect to the slot of a stator core, a coil of a motor, and a stator of a motor. The coil production method in which one surface of a rectangular conductor is brought into contact with a shaft with guide, and edgewise bending is performed along the curved surface of the shaft, wherein a deforming mechanism for reducing the plate thickness of a plate thickness changed portion corresponding to each of four corners of a coil over the entire width of the rectangular conductor is provided, the deformation mechanism is used to deform the plate thickness changing portion, and the plate thickness changing portion of the rectangular conductor is edgewise-bent to form a coil.
