摘要:The structure and operating principle of a new kind of hybrid magnetic bearing (HMB) with permanent magnets in the rotor are introduced in this paper. Three-dimensional FEM analysis models of HMB are built first, then air-gap flux density distribution under different conditions, X-Y magnetic coupling, and the force-current characteristics are studied in sequence, some of which are compared with other kinds of magnetic bearings to throw light on the advantages of the presented HMB. A prototyped HMB is manufactured in the application of the satellite attitude control/energy storage flywheel system with angular moments of 15 Nms at a speed of 30 000 rpm. It is verified by theoretical analysis and prototyped experiments that the proposed HMB features simple structure, low power loss, little X-Y magnetic coupling, good force-current characteristics, and, finally, high operating reliability.
