Abstract :
This paper presents a 3D numerical analysis of the thermal transient behavior of the air-cooled interior permanent-magnet synchronous motor (IPMSM) for agricultural electric vehicle (AEV) using finite-element method (FEM). The air-cooled IPMSM is investigated the temperature variation for the insulation of winding coil and demagnetization of permanent-magnet during the rated operation. Therefore, the prediction of a motor temperature is necessary at the motor design stage. This paper shows a good agreement both the numerical calculation and experimental results. The proposed method, electromagnetic field and thermal linked analysis, is able to predict the temperature distribution of IPMSM with the rated 7.5 kW continuous power.
