永磁同步电机转子初始位置辨识研究综述

Review on Initial Position Estimation Method of Permanent Magnet Synchronous Motor

当永磁同步电机起动时的初始位置不够准确时,会导致电机起动转矩不足甚至出现反转现象。对永磁同步电机转子初始位置辨识方法进行了综述,对不同方法进行了深入阐述和对比分析,对永磁同步电机转子初始位置辨识技术的发展进行了展望。

If the permanent magnet synchronous motors starts without an accurate initial position,the starting torque of the motor will be insufficient or even reverse.The methods of rotor initial position identification for permanent magnet synchronous motor were reviewed,different methods were expounded and compared,and their development was prospected.
