RADIAL MAGNETIC BEARING FOR THE MAGNETIC BEARING OF A ROTOR

摘要

A radial magnetic bearing for magnetic bearing of a rotor has a stator which includes a magnetically conductive stator element, arranged circulating around a rotor. The stator element has recesses running in the axial direction of the stator element in which electrical lines from coils are arranged, wherein magnetic fields can be generated by the coils which hold the rotor suspended in an air gap arranged between the rotor and stator. A softer progression of the components of magnetic flow density in the radial direction is achieved by design measures on the transitions from one magnetic pole to the next magnetic pole, which results in a reduction of the eddy currents induced in the rotor
