In order to improve the transmission system of the whole vehicle on the basis of the original structure of the mine engineering vehicle, higher requirements are put forward on the volume of the traction motor. However, it is found that the conventional radial motor cannot meet the volume requirements. Therefore, an axial flux permanent magnet motor is designed, which can not only meet the spatial volume requirements of the motor, but also meet the requirements of operating conditions. In order to ensure the stable operation of the motor under any kind of operating conditions, the finite element analysis of the no-load and load conditions is carried out, the water structure of the motor is designed, and the finite element analysis is carried out on the temperature of the motor and the mechanical strength of the rotor.
