ABSTRACT:
A method of manufacturing a motor that includes a permanent magnet unit disposed at a circumference for providing a plurality of magnetic poles, and a rotor disposed inside the circumference to be coaxial with the said permanent magnet unit. The rotor includes a center core coaxial with the center axis of the rotor, a plurality of coil cores disposed at peripheral portions of the rotors, and a plurality of concentrated coils respectively mounted on the coil cores. The method includes simultaneously: holding all of the coil cores by peripheral portions thereof so that outer peripheries of the held coil cores are on a prescribed circle, punching corners of one end of the center core to form chamfered corners; and moving the held coil cores from the end of the center core where the chamfered corners are formed so that the center core can be completely fitted to the held coil cores.
