| Abstract: | The hybrid excitation starter generator (HESG) of range-extended electric vehicles is at risk of permanent magnet (PM) demagnetization under overload conditions. Therefore, this paper analyzes the operating process of PMs and the impact of armature reaction fields on PM operating points and demagnetization under various operating conditions. The variation patterns of average flux density operating points and minimum flux density values in the HESG under different load conditions are derived. The demagnetization points of each PM and their contributing factors are determined. Furthermore, the parameters of the magnetic isolation air gap between the PMs are optimized while considering leakage flux and demagnetization at the ends of the PMs. The simulation analysis and prototype test results show that a reasonable design and optimization of the ends of PMs can effectively enhance the demagnetization resistance of PMs and improve the output performance of HESG.
