Electromagnetic actuator for e.g. vehicle gearbox, has measuring device measuring position of palette, microprocessor controlling electromagnets to deliver high force of attraction, and control circuit controlling movement of actuator

摘要

The actuator has a mobile palette (8) oscillating around an axis and placed between two electromagnets. A measuring device measures the position of the palette by measuring a variation of inductance of a coil. A microprocessor controls the electromagnets to deliver a high force of attraction. A control circuit controls a linear or oscillating movement of the actuator.
