Abstract (en)
[origin: WO2008074045A2] The invention relates to a magnetic bearing device (1) for the non-contact bearing of a moving object (2), such as a shaft, with a stationary bearing part (2), a permanent magnet system (11) with at least one permanent magnet (4, 4A, 4B) for generating a magnetic base flux (7, 8) and with a control winding system (13) having at least one control winding (14, 15, 16) for generating a control flux (20), which can be supplied with a control current (i), dependent on the deviations during operation of the body (3) from the set position. Measuring means (36, 37, 38, 39) are provided for measuring an inductivity change in the control winding system (13) occurring on a deviation of the body (3) from the set position and/or an electrical parameter related to a voltage induced in the control winding system (13), from which the control current is derived.
