基于空间等效阻抗模型的永磁同步电机初始位置检测

Accurate initial position detection is important for enhancing the start-up performance of permanent magnet synchronous motors (PMSMs). However, the conventional high-frequency (HF) injection methods make it difficult to estimate the accurate initial position in PMSMs with low saliency ratios and significant cogging harmonics. To address these issues, this article proposes a spatial equivalent imp...
