中文摘要：
为减少无轴承同步磁阻电动机的传感器成本，提高其实用性，提出了一种基于高频注入法的无径向位移自检测方法。通过在无轴承同步磁阻电动机转矩绕组中注入脉动高频电压信号，利用电机空间凸极效应及其转矩绕组和悬浮力绕组之间的互感，实现对转子径向位移的有效预测。采用MATLAB仿真软件构建了仿真系统，仿真试验表明该自检测方法能实现对无轴承同步磁阻电动机转子径向位移准确预测，并能实现无传感器方式的稳定悬浮运行。
英文摘要：
To reduce sensor cost of a bearingless synchronous reluctance motor and improve its practicability, a scheme using fluctuating high frequency voltage signal injection to estimate rotor radial displacement was suggested. The method was based on bearingless motor space-saliency effect and torque windings and suspension force windings~ mutual inductance, the rotor radial displacement was observed simultaneously by injecting fluctuating high frequency voltage signal into torque windings. The simulation system of radial displacement self-test of the bearingless synchronous reluctance motor was set up by using MATLAB, and the simulation test was carried out. The simulation results demonstrates that proposed method is ca- pable of precisely estimating rotor radial displacement and can achieve stable sensorless suspension operation.
