基于非对称相绕组的表贴式永磁同步电机脉动高频信号注入技术

Magnetic saliency based techniques have been widely used in permanent magnet synchronous motor (PMSM) drives to detect rotor position and speed, especially during the starting and low speed operations. Among these techniques, pulsating high frequency signal injection (PHFSI) stands out as a commonly used technique in various industrial applications. However, a significant limitation arises when ap...
