Abstract
An actuator element of an electromagnetic transducer which converts an electric current into an associated mechanical variable, for example an oil pressure, a displacement or a force, has hysteresis which is reduced by the fact that a periodic fluctuation component (jitter current) is superimposed on an actuator current. The influence of the operating parameters of the actuator element (for example of the temperature) on the hysteresis is eliminated by the fact that the frequency or the amplitude of the fluctuation component is varied in dependence on the operating parameter.
