Abstract

PURPOSE:To reduce the size of a step motor and to facilitate the assembling of the motor by mounting an oscillator block in which a crystal oscillator and so forth are sealed on one end of a coil frame, containing the block in a cylindrical stator yoke, and confronting the rotor with the teeth of a magnetic pole. 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 on one end face of a stator coil frame 4 to manufacture a coil frame block. This block is contained in a cylindrical stator yoke 9 opened at one end having teeth of a magnetic pole, a cover 10 is mounted on the opening end, a disk-shaped rotor 12 is journaled on a shaft 7 projected from a yoke 9, and confronted with the teeth of the magnetic pole. Thus, the entire step motor can be reduced, and the assembling of the motor can be facilitated.
