Abstract
A device for detecting position of a rotating working means in an active magnetic bearing which comprises sensors (A, B) of the position of a rotating working means, detectors (D) of an output signal of the sensors (A, B) and evaluation circuits connected to control system of the active magnetic bearing. The sensors (A, B) of the position are composed of high frequency transformers, each of which is directly connected to the detector (D) of its output signal and the detectors (D) are composed of an electrical quadrupole with a non-linear transfer characteristic.
