| Abstract: | Using the concept of multiple degrees of freedom in multiphase machines,this paper adopts an SVPWM control algorithm for a 5-phase permanent magnet type bearingless motor.The appropriate voltage vectors are selected in torque plane and suspension plane,and according to the prompt feedback in both planes and the algorithm proposed,the applying time of each voltage vector and the conducting time of power electronics devices are carried out.Conventionally,space voltage vectors in harmonic plane are used to ame... |
