摘要
提出了一种用于定子单绕组无轴承开关磁阻电机(Bearingless switched reluctance motor,BLSRM)的转子位移控制方法.首先介绍了定子单绕组无轴承开关磁阻电机的基本结构和工作原理,基于等效磁路法建立悬浮力和刚度的数学模型.其次,建立了转子动力学模型以获取悬浮力与转子位移间的关系模型.最后,设计了一台实验样机并在电机上进行悬浮控制实验.实验结果验证了所提控制方法的有效性.
Abstract
Rotor displacement control of a bearingless switched reluctance motor(BLSRM)with single-winding stator is proposed.First,the structure and working principle of BLSRM are briefly introduced.The equivalent magnetic circuit method is used to establish a mathematical model of suspension force and stiffness.In addition,a rotor-dynamic model is established to attain the relation between force and rotor displacement.Finally,a prototype motor is designed and the suspension control of the motor is implemented.The validity of the proposed method is verified by experimental results.
