Clutch and/or gearbox actuator

摘要

The actuator (1) has an electric motor (2) and an incremental encoder. The occurrence of a non- plausible signal status closes the current supply to the electric motor. The encoder collects the operating temperature of the electric motor by a temperature control device. The encoder is provided in such a way that with the occurrence of an operating temperature lying outside of the desired value range, a situation measuring signal layer (5) of non- plausible signal status is provided.
