PURPOSE:To provide a motor which can be manufactured easily, enhances output efficiency, and reduces wearing of a bearing by making a stator coil of single winding. CONSTITUTION:A stator coil 13 comprises a winding formed cylindrical. Both ends of the stator coil 13 are provided with stator magnetic poles 17, 18 with salient poles 17a, 18a projecting in the periphery. The magnetic poles of a cylindrical permanent magnet rotor 21 face the salient poles 17a, 18a. The permanent magnet rotor 21 is magnetized in heteropolarly magnetized alternately in the circumferential direction. The magnetic field of the permanent magnet rotor 21 is detected by a magnetic sensor 31, so that the energizing direction of the stator coil 13 is switched according to positions of the permanent magnet rotor. |
