AB - Due to the insulation aging, demagnetization and other problems of the  permanent magnet and insulating material in the permanent magnet  synchronous hub motor under high temperature, the numerical simulation of  the heat dissipation of surface mounted permanent magnet synchronous hub  motor is proposed. According to the heat transfer of hub motor, the effect  degree of heat conduction, heat convection and heat radiation is obtained,  the heat transfer coefficient of each part is calculated, and the influence  of motor insulation material on temperature rise is analyzed. The  experimental results show that the heat dissipation of hub motor under  natural cooling condition is poor, and the internal oil cooling method can  effectively improve the heat dissipation of hub motor and reduce the  temperature difference. When operating at high speed, this reduces the  potential safety hazard.
