Abstract

PURPOSE:To reduce the size of a step motor by mounting an oscillator block at one end of a coil frame through which an iron core is inserted and forming a magnetic circuit by bringing a stator piece attached to an iron core into pressure contact with the inner surface of a yoke when assembling the block in the cylindrical yoke. CONSTITUTION:A crystal oscillator, a frequency divider, a drive circuit and so forth are sealed in a cylindrical oscillator block 1, and the block 1 is mounted at one end face of a stator coil frame 4. An iron core 6 is passed through the hollow portion of the frame 4, and a stator piece 8 made of magnetic unit is attached to the iron core 6. A magnetic circuit is formed with the iron core 6, the yoke 9 and the stator piece 8 by bringing the end 9a of the piece 8 into pressure contact with the inner peripheral surface of the yoke when containing the coil frame unit A in the yoke 9. A disk-shaped rotor 12 is rotatably supported to the shaft 9 projected through the teeth of the yoke 9.
