摘要： A sensor system for a magnetic bearing, which has two actuator coils, two clocked power output stages, a current sensor for detecting those currents in the actuator coils which are encumbered with a ripple current, and a sensor interface. The clocked power output stages provide a pulse-width-modulated output voltage, the pulse width of which is narrowed or widened by small amounts in a predefined order, and the pulse widths of the clocked power output stages are modulated in a fixed phase relationship with respect to one another. The sensor system specifies a sensor system for a magnetic bearing with a clocked power output stage. A magnetic bearing, a control device for a magnetic bearing and a method for detecting the position in a magnetic bearing are also disclosed.
