ABSTRACT:
A motor includes a rotor including a permanent magnet circumferentially equally divided and alternately magnetized to different poles into a cylindrical shape. A first coil and a second coil are displayed inside and axially of the rotor. First outer magnetic poles and first inner magnetic poles are excited by the first coil and are opposed to the outer peripheral surface and inner peripheral surface of the rotor, respectively. Second outer magnetic poles and second inner magnetic poles excited by the second coil are opposed to the outer peripheral surface and inner peripheral surface of the rotor, respectively. The first inner magnetic poles and the second inner magnetic poles are located between the first coil and the second coil, to thereby make the opposed area of the outer magnetic poles, the inner magnetic poles and the magnet large and provide a super-compact motor of a high output and high efficiency.
