PURPOSE: A DC motor is provided to achieve a simplified power supply structure, while allowing the motor to rotate at a constant speed without causing cogging. CONSTITUTION: A horizontal radial linear coil group(613) is formed by arranging a plurality of conductors(213) in a radial form between circular equipotential conductor sections(313), in such a manner a radial current flows between two circular equipotential conductor sections having different diameters. The horizontal radial linear coil group is formed integrally with a stator, and a bipolar permanent magnet(109) is arranged integrally with a rotor, in such a manner that the pole faces of the bipolar permanent magnet are opposed each other, being directed toward a radial direction, in upper or lower sides of the horizontal radial linear coil group.
