Power loss analysis for five phase PMSM drive system with high-resistance connection fault

High-resistance connection (HRC) is a common electrical fault in the electric machine drive system. This paper presents the power loss analysis of five phase permanent magnet synchronous motor (PMSM) drive system with HRC fault. In this paper, the model of five phase PMSM is given under healthy and HRC fault conditions. The power loss, mainly focusing on the copper loss under HRC fault condition is studied, which provide the convenience for further research on how to reduce the power loss under HRC fault condition. The control strategy of five phase PMSM is introduced. The simulation is carried out to quantitatively study the copper loss of the PMSM drive system under healthy and fault conditions.
