Magnetic radial bearing has stator of magnetic material with pole teeth rotor periphery, 3 windings in star or triangle circuit to stimulate pole teeth and 3-phase electric current controller

摘要

The magnetic radial bearing has a stator (30) of magnetic material with several pole teeth (31-33) mounted on the periphery of the rotor with mutual separation, three windings (34-36) connected in a star or triangle circuit to stimulate the pole teeth and a three-phase electric current controller (37) for controlling a three-phase electric current flowing through the three windings.
