Abstract
A magnetic bearing apparatus is proposed having a stator () which includes a winding () for the generation of a magnetic control field, having a rotor () which can be magnetically journalled with respect to the stator () and also having a sensor device () configured as an eddy current sensor for the determination of the distance between the stator () and the rotor (), wherein the sensor device () includes at least one sensor element () configured as an inductor and at least one capacitor () which forms an electrical resonant circuit with the inductor, and also having a monitoring unit () for the control of the sensor device () and for the evaluation of the detected signals. The inductor is arranged electrically in series to the capacitor () so that the electrical resonant circuit is a serial resonant circuit.
