Abstract:
1. A stator manufacturing method of forming a stator by mounting a coil on a teeth portion formed in a stator core through an insulator, the method comprising: mounting the coil on the insulator, the insulator having been formed in a shape that contacts with a side surface of the teeth portion and provides a space between the insulator and an end face of the teeth portion, placing the coil mounted on the insulator in a molding die, injecting a resin into the molding die containing the coil mounted on the insulator to cover a surface of the coil a resin-molded portion by resin molding to form a coil unit, such that, when the coil unit is mounted on the teeth portion, the resin is not in the space between the insulator and the end face of the teeth portion, mounting the coil unit on the teeth portion of the stator core, and bonding or welding the coil unit and the side surface of the teeth portion, wherein
