Document Type and Number:
Japanese Patent JPS59169357
Kind Code:
A
Abstract:
PURPOSE:To enhance the dimensional accuracy and to improve the assembling property by forming double cylinder in which a coil is annularly disposed concentrically with a rotor and yokes are disposed in inner and outer peripheries of the coil, and partially providing outer and inner peripheral connectors at both axial ends in a circumferential direction. CONSTITUTION:A shaft 11 is integrally mounted on a rotor 1. A yoke 3 disposed on the outer periphery of 2-pole magnetized portion 8 of the rotor 1 in a stator 2 are formed in double cylinder and contained so that coils 5, 6 are axially aligned between the outer and inner peripheral sides, and the yoke 4 disposed on the outer periphery of the 4-pole magnetized portion of the rotor 1 contains a coil 7 between the outer and inner peripheral sides in double cylinder. The coils 5-7 are all annularly formed concentrically with the rotor 1. The yokes 3, 4 are partly provided with a connector 10 for connecting the outer peripheral side and the inner peripheral side at both axial ends. The position of the rotor 1 is detected by a magnetosensitive element 14 to turn transistors 15, 16 ON and OFF, thereby controlling the currents of the coils 5, 6 to rotate the rotor 1.
