摘要
利用旋转高频信号注入法面贴式永磁同步电机转子位置时,由于各种因素的影响,高频负序电流中将含有各种谐波,这些谐波给转子位置的估计带来极大的误差。本文对这一问题进行了理论研究和实验验证,初步阐释了负序电流谐波产生的原因及造成的影响,并提出了相应的解决办法。
When using the method of rotating high - frequency voltage injection to estimate the rotor position of Surface- Mounted Permanent- Magnet Machine（ SMPMM）, the negative current harmonics, which resulted from the asymmetry of the distribution of high - frequency inductance , wilt give rise to some errors to the rotor position estimation. This paper discussed this issue from both hand of theory and experiment, and primitively demonstrated the reason the negative current harmonics occurred and its effects. The measures to solve it were also presented.
