摘要
介绍一种具有较宽调速范围的无位置传感器无刷直流电机转子位置检测新方法——反电势 3次谐波检测法。从理论上推导了如何从电机中获取反电势 3次谐波信号 ,并将 3次谐波信号转化成转子磁通位置信号。
This paper describes a novel sensorless method for rotor flux position for brushless permanent magnet motor operating over a wide speed range, by detecting the third harmonic signal of back-emf. How to obtain the third harmonic signal and then to transform it to the signal of rotor flux position is discussed in the paper. Effectiveness of this method is verified by the results of the experiment.
