Abstract: Magnetic bearings operate contactlessly and are therefore free of wear and lubricant,which have innovated the traditional supporting forms fundamentally.Introduced the basic theory of AC 2DOF homopolar HMB and given the figure of control system.Based on TMS320F2812 DSP,had manufactured the hardware of control system,especially designed the drive system and developed the software.
