Abstract

Magnetic bearing device (1) for non-contact mounting of a moving body (3), such as a shaft, with a stationary bearing part (2) with an electromagnet system (11), which, during operation, may be supplied with a control current dependent on the deviation of the body (3) from the set position and, in at least one free space (60) between system components of the magnetic bearing device (1), in particular, within return loop parts (5, 6), at least one electrical or electronic component (50-55), such as a control circuit component, a power circuit component and/or a power supply component is housed.
