“…4059-4066 teristics will change fundamentally, and the insulating ability will be lost seriously [7]. The temperature rise limit of the winding is basically determined by the maximum allowable temperature of the insulating material of the insulating structure and the temperature of the cooling medium [8,9]. Starting from the selection of motor materials, the selection of high insulation and high temperature resistant insulation materials is one of the most effective methods to improve the efficiency of the motor's heat dissipation.…”

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.
