Gearbox controlling device for motor vehicle, has electrical actuator with coil formed by turns of wires, where number of turns in direction perpendicular to plates is six times lower than number of turns in coil`s displacement direction

摘要

The device has a flat electrical actuator comprising a coil (42) that is formed by turns of conductor wire wound on a support surrounding an intermediate plate (32) of a yoke. The coil is placed between flat permanent magnets (48, 50) that are respectively fixed on a lower plate (30) and an upper plate (34) of the yoke. The number of turns in direction perpendicular to the plates is six times lower than the number of turns in displacement direction of the coil.
