Abstract
A rotor for a self-starting permanent magnet AC motor is comprised of a permanent magnet disk mounted on a shaft of non-magnetic material. The magnet has a direction of magnetization parallel to the axis of the shaft resulting in two poles, one on each face of the magnet. Two disks of current carrying material are mounted on the shaft on either side of the magnet to act as starting coils. Pole pieces are mounted on the shaft and surround the starting disks. Claw-like projections spaced about and extending from the periphery of the pole pieces extend inwardly over the periphery of the magnet and starting disks. The claw-like projections from each pole piece are interlaced forming rotor poles of alternating polarity.
