Abstract
The bearingless permanent magnet synchronous motor (BPMSM) is an innovational type of motor, which has all excellence of magnetic bearings. In the paper, based on the basic working principle of BPMSM, the mathematical models of the radial forces and rotation part on BPMSM are deduced by adopting rotor magnetic field oriented control strategy. A digital vector control system according to the demand of decoupling is designed by using TMS320LF2407 DSP technique. The hardware and the software of the digital control system are developed in this paper. The experimental results have shown that the steady suspension of the rotor is realized and the speed of the rotor can be continuously adjusted within the range of 0〜3 000 r/min.
