Abstract
An actuator device (6) with an electromagnetic actuator (3) which has first and second magnet coils (4, 5) and a shift element (3) which can be linearly shifted, between three stable positions, by the first and the second magnet coils (4, 5). The actuator device (6) has a shifting bridge (9), with three bridge branches (B1, B2, B3) connected in parallel, for controlling the magnet coils (4, 5). Each bridge branch (B1, B2, B3) has two switches (S1 . . . S6) connected in series. One of the first and the second magnet coils (4, 5) is connected in each of the two bridge diagonals (D1, D2). In addition, a method for the control of the magnet coils (4, 5) of an electromagnetic actuator (2) of the actuator device (6).
