| Zusammenfassung: | PURPOSE:To simplify the structure and to reduce the size of a spiral pulse motor by integrating a pulse motor which rotates and operates a linear pulse motor which operates axially at a rotational shaft. CONSTITUTION:When a pulse current is inputted to a stator winding 1, a stator pole 2 is excited, and a rotor pole 6 disposed at the nearest position to the pole 2 is attracted. Therefore, a rotor 7 is rotated. The rotating angle of the rotor 7 can be controlled by controlling the pulse current inputted to the winding 1. When the pulse current is inputted to a movable element winding 12, a movable element pole 11 is excited, and is attracted to a relative stator pole 9 disposed at the nearest position to the pole 11. The position of the element 14 can be controlled by controlling the pulse current inputted to the winding 12. |
