Patent ID: 7275299

Claim:
A method for manufacturing a motor with a ring-shaped motor core having slots formed in an inner circumference of the motor core and in which coils are inserted and arranged in the slots, comprising: forming a plurality of single-pole coils that include two coil insertion portions and two coil end portions that connect the coil insertion portions; and inserting the coil insertion portions into the slots, by: retaining the single-pole coils at or after the forming of the coils; arranging the single-pole coils such that the coil insertion portions of each of the single-pole coils confront openings of the slots and are generally parallel to an axial direction of the motor core; moving each of the single-pole coils substantially linearly toward the motor core such that each of the single-pole coils move from a retained position and a moving direction of adjoining coil insertion portions, before the adjoining coil insertion portions of adjoining single-pole coils are inserted into the slots, are substantially parallel or approach each other from an inner circumference side to an outer circumference side; and moving the two coil insertion portions of each single-pole coil such that the coil insertion portions start moving simultaneously and at equal velocities, wherein: the formed coils are placed in a magazine before the coils are inserted into the slots, the magazine has such a shape such that the magazine can be arranged on an inner side of an inner circumference of motor core, which the magazine is provided on an outer circumference with a plurality of coil retaining grooves at positions confronting the slots of the motor core as to arrange the coil insertion portions of the single-pole coil, and in which the coil retaining grooves for arranging the adjoining coil insertion portions in the adjoining single-pole coils are arranged either in parallel with each other or to approach each other from the inner circumference side to the outer circumference side; the coil insertion portions of the single-pole coils are inserted into the coil retaining grooves to retain the coils on the magazine; the magazine is so arranged inside of the motor core that the coil retaining grooves of the magazine may confront the slots of the motor core; and all of the single-pole coils are moved from the coil retaining grooves to the slots of the motor core by bringing a coil insertion into abutment against all of the single-pole coils on the magazine thereby to advance the abutting portions in the direction from the center of the magazine to the outer circumference.
