摘要
本文针对传统的三次谐波法检测直流无刷电机系统存在的一些问 题,提出了一些使设计更为简单,使检测可靠性和准确度更高的措施。实际试验 表明,这种方法能够准确而快速地估计转子位置,动静态特性良好,整个系统结 构紧凑,可靠性高。
A new method of sensing rotor shaft position of BLDCM (Permanent Magnet Brushless DC Motor) is presented based on the third harmonic component sensing . It is applicable to the BLDCM with trapezoidal back EMF waveform. The presented method is of higher reliability and higher precision compared with the conventional 3 rd harmonic sensing method. The experimental results are performed to verify the validity of the proposed method.
