| Abstract: | For a 12/8-pole doubly salient permanent magnet (DSPM) motor,the formulas for equivalent inductance during every working region were analyzed.Then the equivalent inductance characteristics were given based on numerical calculation method under ANSOFT simulation environment. The influences of equivalent inductance on winding current slew rate, chopping frequency,and system closed-loop design were given,and it provided a reference guideline for the appropriate design and control of DSPM motor. |
