Abstract :
The doubly salient permanent magnet (DSPM) motor is a new type of brushless machine and it offers advantages of high power density, wide speed range and simple structure. In this paper, a new drive topology for improvement of torque-ripple and fault-tolerance in an 8/6-pole DSPM motor is proposed. Based on co-simulation of magnetic and electrical circuit solvers, analysis of the proposed topology are performed, such as operation characteristic and performance under various conditions. Finally, the proposed topology is experimentally validated. The simulation and experimental results show that the proposed topology can enhance the electromagnetic performance of faulty operation, and lay a foundation for the further research on fault tolerant strategy.
