为了在矿用工程车原有结构的基础上改善整车的传动系统，对牵引电机的体积提出了较高的要求。然而，通过研究发现，常规的径向电机不满足体积要求。因此，设计了一款轴向磁通永磁电机，既能够满足电机的空间体积要求，也能满足运行工况的要求。为了保证电机在各种工况下均能稳定运行，对电机的空载与负载、温度与转子机械强度进行了有限元分析，并设计了电机的水路结构。

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.
