Actuator for an adjustable spring plate

摘要

The device has a first unit, on which an actuator is supported that is a synchronous motor whose rotor position relative to its stator is determined by a sensor arrangement and axially adjustable by a first spring plate, a second unit interacting with a second spring plate and a spring between the spring plates. The sensor is a plate sensor (51) whose input part (53) is attached to the rotor (29) and whose output part (55) is attached on the stator side.
