At present, the precision of this method is nearly good as that of ten-bit encoder. But there are some questions for estimating position polarity. Based on high frequency signal injection, this paper presents a method to compensate position polarity for permanent magnet synchronous motor (PMSM). Experiments were performed to test the effectiveness of the proposed algorithm and results present the good performance. }, journal = {International Journal of Electronics and Communication Engineering}, volume = {3}, number = {10}, year = {2009}, pages = {1852 - 1856}, ee = {https://publications.waset.org/pdf/7138}, url = {https://publications.waset.org/vol/34}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 34, 2009}, }
