<p>PURPOSE: To shorten response time, by providing a rotating actuator which moves by a rotating magnet and has a return spring, determining the angle position by a mean value of a pulse current and removing magnetizing energy in the magnet. CONSTITUTION: A mechanical part 1 is connected to a rotating actuator 11 by a transmission 12, and the transmission 12 connects the rotating motion of the rotating actuator 11 to a linear motion of the mechanical part 1. The rotating actuator 11 is moved by a rotating electromagnet mechanically fixed. Rotating electromagnet, that is, the angle position of the rotating actuator 11, is determined by a current supplied by an electronic module 13. A concentric spring 14 gives a couple of force opposite to that of the rotating electromagnet and returns the rotating actuator 11 to its initial position. Means 15 for reading the angle position of the actuator 11 sends an electric response showing the position to an electronic module 13 and permits the control of angle position of the actuator 11.</p> |
