摘要
转子位姿检测是磁悬浮球形磁阻电动机运行的重要环节,它包括了转子的位置检测和姿态检测。在球形磁阻电动机上建立三维坐标系,推导出转子姿态的描述方法。提出基于径向位移传感器和角位移传感器计算转子姿态的方法,该方法通过球面的几何关系,由传感器检测出的数据计算出球体的姿态矩阵,通过坐标系的旋转与位置变换算出球体上任意一点的位置坐标。
Detecting rotor position is an important part of work of magnetic suspension spherical reluctance motor.It contains rotor＇s position and orientation detection.This paper creates three-dimensional coordinate system on spherical reluctance motor,derives the description of the rotor＇s position and orientation and proposes a method for calculating rotor＇s position based on radial displacement sensors and angular displacement transducer.It also uses this approach and the spherical geometry relation to calculate orientation matrix of rotor according to the data from the sensors,so we can work out the position of any point through the rotation of coordinate system and position transformation.
