Abstract :
Compound-structure permanent-magnet synchronous machine (CS-PMSM) is a solution to realize both the torque and speed control of the internal combustion engine (ICE) for hybrid electric vehicles. It can enable the ICE to operate at the optimum efficiency during all driving conditions. In this paper, a novel radial-radial flux CS-PMSM is designed, and its magnetic coupling is analyzed. Based on the special structure of CS-PMSM, A series of methods of optimizing cogging slot torque are investigated. The purpose of optimizing cogging slot torque is realized, by establishing and analyzing a series of models. The final results of analysis and optimization has important meaning to the further research of CS-PMSM used for HEV.
