    摘 要:提出一種靜態頻率響應檢測永磁同步電機d軸電感和q軸電感的方法,介紹了該方法的測量原理及實驗步驟,該方法讓轉子停留在任意給定的位置,無需在檢測過程中校準永磁轉子位置而避免由于位置不精確導致測量誤差。將該方法應用于SPM和IPM電機的電感檢測,通過調整交流電源的電流、頻率和永磁電機轉子磁極的位置等多維度下檢測的數據,驗證了該方法的檢測數據和有限元仿真計算數據相接近。將檢測參數應用到SPM和IPM的電機控制中,驗證了該檢測方法數據在工程應用中的有效性及優越性。

    Abstract: This paper introduced a standstill frequency response method for measuring d-axial inductance and q-axial inductance of permanent magnet synchronous motor (PMSM) during PMSM development and design processing.The method is applied with the rotor at standstill in a given arbitrary position, without requirement of calibration for the rotor position in testing; it is avoid measurement errors due to inaccurate position.Meanwhile, this method was applied to the SPM and IPM motor inductance detection, adjusting the output current and frequency of AC power supply and the position of PMSM rotor to verify the consistency between detection data of this method and FEA (finite element analysis)result. Finally, the validity and superiority of this detection method in engineering application are verified by applying the parameters to the control of SPM and IPM.
    Key words: permanent magnet synchronous motor (PMSM); frequency response; d-axial inductance; q-axial inductance; FEA
