Abstract: A single-phase motor which includes a rotor magnet alternately magnetized to different poles by dividing it along a circumferential direction and in which a coil is disposed in an axial direction of said rotor magnet. Outer magnetized portions of an outer yoke magnetized by the coil and inner magnetized portions of an inner yoke magnetized by the coil are opposed to outer and inner peripheral surfaces of the rotor, respectively. There is also provided a holder for holding the rotor magnet at a position where centers of magnetic poles of the magnet are deviated from a straight line connecting centers of the outer magnetized portions and a rotational center of the magnet when the outer and inner magnetized portions are not magnetized. The inner yoke has a small diameter portion, and, only by reducing the diameter of the small diameter portion, the space within which the coil is wound can be widened so that the coil can be wound around the small diameter portion greatly, thereby providing a single-phase motor having high output.
