Numerical analysis of thermal and mechanical field in the high temperature permanent magnet synchronous machine

Abstract : The paper describes a 3D analysis of the thermal field in permanent magnet synchronous machine able to work at high internal temperature (HT machine). The 3D coupled fluid-thermal and mechanical model of the machine is employed to obtain the distribution of thermal field and the airflow; it calculates the average temperature of the most sensitive parts such as coils and permanent magnets. The impact of the magnetic wedges closing the slots on the cogging torque and temperature distribution is analyzed. The points of the highest temperature inside analyzed machine are localized too. The computer simulations are compared with the measurements.
