COIL PRODUCTION METHOD, COIL OF MOTOR, AND STATOR OF MOTOR

摘要

A coil production method capable of improving the space factor of a straight angle 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-section straight angle conductor (15) is brought into contact with a guided shaft (83), and edgewise bending is performed along the curved surface of the guided shaft (83), wherein a deformation mechanism (62) for reducing the plate thickness of a plate thickness changing portion (15a) equivalent to one of the corners of a coil over the entire width of the straight angle conductor (15) is provided, the deformation mechanism (62) is used to deform the plate thickness changing portion (15a), and the plate thickness changing portion (15a) of the straight angle conductor (15) is edgewise-bent to form a coil.
