摘　　要：采用载波注入方法估计内埋式永磁同步电机 (IPMSM)转子的初始位置 ,并应用磁饱和效应鉴别转子的磁极极性。同时还讨论了应用旋转矢量、载波励磁和位置观测器来跟踪转子位置。This paper presents a method to estimate the initial rotor position and magnet polarity for an interior permanent magnet synchronous machine (IPMSM) based on carrier frequency injection. The method using rotating vector, carrier frequency excitation and observers for tracking position is discussed. The simulation and experimental results show good response of the position observer and the feasibility of the method.
