【Abstract】 The doubly salient permanent magnet motor(DSPM) is a new kind of AC brushless motor. The mutual inductance of DSPM has a same value to the self inductance and cannot be neglected. This paper analyzes the influence on the mutual inductance done to the current characteristics. Firstly the formula of the mutual inductance from the equivalent magnet circuit of DSPM is given; Then, from the aspect of the control circuit and the mathematical model, the influence on the mutual inductance done to the current characteristics of the DSPM is theoretically studied. Finally simulational example is gvien. Analysis and simulation prove that the mutual inductance of DSPM has influence on the current characteristics in each process.更多还原
