ABSTRACT:
In a motor, a rotor made of a permanent magnet which is equally divided in the circumferential direction to be alternately magnetized to different poles is formed into a cylindrical shape. The first coil, the rotor, and the second coil are sequentially arranged in the axial direction of the rotor. The first outer and inner magnetic poles excited by the first coil are set to oppose the outer and inner circumferential surfaces, respectively, of the rotor, and the second outer and inner magnetic poles excited by the second coil are set to oppose the outer and inner circumferential surfaces, respectively, of the rotor. An electric element is arranged at a position to oppose, across a predetermined gap, the circumferential surface of the permanent magnet not covered with the first or second outer magnetic pole. Alternatively, an electric element and a circuit pattern are formed on a connection member that connects the first and second outer magnetic poles to each other.
