摘要

Demagnetization in permanent magnet synchronous machine (PMSM) is a special and common fault which greatly reduces the motor's efficiency, and thus an electric vehicle's performance. In this paper, we propose a method to estimate the motor's operating efficiency reduction after a certain flux density degradation. The aim is to reflect the relationship between the PMSM complete demagnetization and the resultant efficiency variation. The demagnetized motor is also introduced into the energy management of a plug-in hybrid electric vehicle (PHEV) based on dynamic programming to investigate its influence on the energy consumption. Simulation results indicate that the fuel economy reduces tremendously when the flux-density degrades by 20% and over.
