Abstract
PURPOSE:To reduce the size of a step motor and to enhance the reliability of the motor by containing an oscillator block in which a crystal oscillator and so forth are sealed in the hollow section of a ring-shaped coil frame, associating the block in a plate-shaped yoke formed with teeth of a magnetic pole, and coupling it with the outer peripheral edge. CONSTITUTION:A crystal oscillator, a capacitor, a frequency divider, an inverter and so forth are sealed in a cylindrical oscillator block 1, and the block 1 is contained in the hollow section of the coil frame 4 of a ring-shaped coil 5. This coil frame 4 is contained in a plate-shaped yoke 6 fromed with teeth 9 of a magnetic pole on one surface, and the outer peripheral edge of the bottom surface of the coil frame 4 is coupled with the opening end of the yoke 6. A disk-shaped rotor 12 is journaled on a shaft 7 projected from the center of the teeth 9, and confronted with the teeth 9. Thus, the thickness of the entire motor can be reduced, and since the oscillator and so forth can be shielded, the reliability of the motor can be improved.
