Abstract
An electromagnetic drive includes a stator, having a stator holder and an actuating element which is movable by electromagnetic interaction with the stator. The stator holder has at least two electrically conductive paths running separately from and adjacent to one another. In each case, the two paths running separately from and adjacent to one another form a path pair, and the paths of the path pair are connected to one another in electrically conductive fashion at their respective ends. The paths of the path pair are arranged such that the stator and/or the actuating element induces eddy currents acting in opposite directions in the paths.
