ABSTRACT:
A motor includes a rotor having a permanent magnet circumferentially equally divided and alternately magnetized to different poles formed into a cylindrical shape, and a first coil. The rotor and a second coil may be successively disposed axially of the rotor. A first outer magnetic pole and a first inner magnetic pole excited by the first coil may be opposed to the outer peripheral surface and the inner peripheral surface of the rotor, and a second outer magnetic pole and a second inner magnetic pole excited by the second coil may be opposed to the outer peripheral surface and the inner peripheral surface of the rotor. The rotor has an output transmitter, such as a gear or a pulley, mounted on the outer peripheral surface of the central portion thereof.
