摘要： A method for measuring a resistance and an inductance of a permanent magnet synchronous motor (PMSM) in a static state includes inputting a rated current of the PMSM and 150% of the rated current at a state of locking an axle of the PMSM, recording corresponding voltages V100% and V150%, and dividing the voltage difference with the current difference to obtain the resistance of the PMSM. The method continues dividing an electrical period into six voltage vectors at a state of vector controlling, and performing four voltage cycles under every the voltage vector. The voltage cycle includes step outputting a quarter of the voltage V150%, and outputting the voltage V150% after the current being stable. After one of the six voltage vectors being finished, the method switches the other voltage vector and repeats the voltage cycles, and the method is completed till all of the six voltage vectors being finished. Finally, the method continues to compare rising times of the voltage vectors and convert the rising times to inductances, and to define the maximum of the inductances as an inductance of a q axis and to define the minimum of the inductances as an inductance of a d axis.
