摘要

METHOD FOR MASS PRODUCING AN INTERIOR MAGNET ROTARY MACHINE AND THE INTERIOR MAGNET ROTARY MACHINE PRODUCED THEREBY A rotor for an interior magnet rotary machine, such as motors and generators, is mass produced by forming an elongated structure. This structure has channels in the periphery thereof which are parallel to the longitudinal axis of the structure. The elongated structure is cut into rotor frames of a predetermined length having channels extending from one end to the opposite end thereof. Magnets are placed in the channels. Pole pieces may be placed on the magnets in the channels. The interior magnet rotary machine produced by this method has a rotor of a structure made of a rotor frame with channels extending from one end to the opposite end, and at least one magnet in a respective one of the channels. Thus, an efficient, low cost, mass producible, and easily assembled rotor for an interior magnet rotary machine is provided.
