Abstract
An actuator for exciting a component of a motor vehicle with vibrations. The actuator has a housing, an electrical coil and a magnet that is movable to a limited extent in the housing.
Claims18
An actuator for exciting at least one component of a motor vehicle with vibrations, the actuator comprising:
- a housing which is configured to be connected to the component;
- an electrical coil which is rigidly connected to the housing and is configured to generate a magnetic field when an electrical current flows through the coil;
- and
- a magnet which is arranged in the housing so as to be movable to a limited extent,
- wherein the coil has a fixed connection to the housing by an adhesive connection of thermally relatively highly conductive adhesive, wherein said adhesive has a thermal conductivity of at least 0.8 W/(m K).
