基于悬浮正交坐标系的永磁无轴承电机复合传感方案

A proper sensing scheme for the bearingless motor (BM), which is designed for the detection of rotational angle position and translational radial displacements of the rotor, is a vital component from the BM control system point of view. However, adopting independent angle and radial displacement sensing methods make a challenge to the integration of BM system. To further improve integration level ...
