摘　　要：建立主轴无轴承电机的动力学耦合控制模型,分析了主轴无轴承电机的机电能量转化,并在一定的性能指标下对系统进行了转子位移、空载转速跟踪精度的仿真,通过理论分析和仿真结果表明,对系统的悬浮控制和转动控制,均具有良好的动静态性能。为今后主轴无轴承电机的悬浮和旋转控制理论分析提供了理论依据。This paper constructs the kinetics coupled model of the bearingless motor. Analyzeing its electromechanical energy transformation, the simulation of the rotor displacement, no-load rotational speed and tracing accuracy is carried out under a certain performance standard. The analysis and the simulation consequence indicate that the accuracy of the control strategy is high, and the dynamic and static performance is well. Therefore, a theoretical basis is provided for the suspension and rotation control of the bearingless motor.
