An actuator for a clutch or gear mechanism in a motor vehicle comprises an electric motor and an incremental encoder. The encoder comprises a position measurement signal output at which a position measurement signal can be output which has a number of different signal states, each of which is assigned to a relative position between a primary part and a secondary part of the electric motor. For the commutation of the electric motor, the position measurement signal output is connected to a position measurement signal input of a control device for a motor winding of the electric motor. The control device comprises a device for checking the plausibility of the position measurement signal and is designed in such a manner that on the occurrence of an implausible signal state the power supply to the electric motor is disconnected and/or the power of the electric motor is limited.
