Micromechanical coil device

Abstract

A micromechanical device includes an actuator moveable along at least one rotational axis, and an electromagnetic type actuating device. The rotor is composed of a wire coil mounted on a moveable frame, which is rotationally integral with the actuator. The coil conducts the electric current. Protruding strands form a loop proximate the torsional beam. In another embodiment, the coil terminates through its two ends located on the moveable frame. The ends of the coil are each welded to one of the metal plates terminating on the moveable frame. Starting from the power supply pads on the fixed frame, the conductive lines transit through the torsional beam to join the ends of coil on the moveable frame. To make several plates going through one of the torsional beams, the beams are isolated electrically by a groove.
