  • Patent number: 10775610
    Abstract: An actuator device and a method for tilting an actuator device. The method includes the steps: conducting electrical current through an electrical conduction device, which is guided via a tilting device of the actuator device, within a first magnetic field that is generated by a permanent magnet device of the actuator device, so that an actuator element of the tilting device is tilted along a first tilting axis as the result of a Lorentz force; and generating a second magnetic field by an electromagnet device of the actuator device in the area of the permanent magnet device, so that the tilting device is tilted along a second tilting axis as the result of magnetic attraction and repulsion.
