An electromagnetic actuator device includes an actuator having an actuator coil and a tappet that can be moved in and against a longitudinal direction. The actuator device includes a sensor device having a transmitter element arranged on the tappet and a sensor element for generating a measurement signal, containing information about a current actual position of the tappet, depending on a magnetic field generated by the transmitter element. The actuator device includes a control unit with a controller, which applies a control voltage to the actuator coil for generating an electromagnetic field during operation in dependence on a position signal based on the measurement signal, so that the tappet moves into a target position. During operation, a stray magnetic field is generated by the at actuator coil, an adaptation of the measurement signal is performed to compensate for the influence on the measurement signal caused by the stray field.

Actuator device and method for compensating for a stray magnetic field in the case of an actuator device

A gear assembly has a gear housing. A first component group is arranged in a first partial area within the gear housing. The first component group includes at least one sensor element and/or at least one actuator. A remote control device is coupled to the first component group so that signals can be exchanged by way of a bus system.
