Bi-directional Electromagnetic-Thermal Coupling Analysis For Permanent Magnet Traction Motor Under Complex Operating Conditions
Temperature rise has an essential effect on the performance and service life of the permanent magnet in-wheel motor (PMIWM) in traction system of electric vehicle (EV) under complex operating conditions. Bi-directional electromagnetic-thermal coupling method is proposed to analyze the electromagnetic loss and thermal characteristics of the PMIWM considering the influence of temperature rise on the permanent magnetic material. The heat dissipation coefficient and electromagnetic-thermal coupling field model of each component of the PMIWM is analyzed. The distribution of electromagnetic loss and thermal of the PMIWM is investigated under constant speed, constant torque and variable speed and variable torque conditions. A 8kW outer rotor PMIWM is employed to study the electromagnetic-thermal coupling characteristics. Simulations and experimental results show that the thermal field of each component of the PMIWM calculated by the proposed bi-directional electromagnetic-thermal coupling method is more accurate than that of the traditional uni-directional electromagnetic-thermal coupling method under complex operating conditions. The effectiveness of the proposed bi-directional electromagnetic-thermal coupling method provides solid supports for the cooling design of the PMIWM under harsh operating environment.
