6/4极无轴承开关磁阻电机悬浮控制原理与实现

Abstract

Abstract: Due to the disadvantages of conventional 12/8 Bearingless Switched Reluctance Motor (BSRM), such as high frequency of commutation, and more windings and power devices required, the 6/4 BSRM is studied in this paper. Based on the analysis of levitation principle, it is necessary to energize two phases at the same time to ensure rotor levitation in the 6/4 BSRM. Accordingly, proper distribution of levitation forces is realized considering the two-phase coupling. A coordinated control method is proposed to regulate the torque and radial levitation forces simultaneously by dividing winding currents into torque and levitation components. The proposed method is implemented by simulation results in MATLAB/Simulink, and the demonstrated performance is also verified by experimental results.

Key words: 6/4 Bearingless Switched Reluctance Motor (BSRM), two-phase excitation, torque, radial levitation force, coordinated controlhttp
