PROBLEM TO BE SOLVED: To obtain a simple volatile remote operation method that does not require external power supplies or electronic control circuits, and converts various mechanical displacement to an electrical signal by one stepping motor for directly controlling the other. SOLUTION: The stator coil windings of stepping motors 1 and 2 are connected directly to each other by an electric wire, and the rotation of a rotor 4 of the stepping motor 2 is controlled merely by electromotive force that is generated when a rotor 3 of the stepping motor 1 is rotated by external force. |
