This paper investigates the heat exchange characteristics of an external ventilated tract of a compact 4-pole electric motor that can be used in transportation. The computational model was created and validated by experimental results. A series of simulations run on neural networks. It is found that the deflection angle and the angle of the fan blades are key parameters that affect the cooling efficiency of the motor. Optimal measures are taken by varying the deflection angle and the exhaust fan blade angle. With the development of technology, the design of electric motors with high efficiency and high specific power is increasingly used in transport. The compact high voltage motor has the advantages of: compact structure, high power density and high electromagnetic component. However, increasing the power density will inevitably lead to more serious consequences, namely the problem of overheating, which will reduce engine power and efficiency. As a solution controlling the range, increasing temperature, which is a key factor, affects the performance and efficiency of the overall design. Therefore, it is necessary to analyse the flow field and the exact temperature field and improve the cooling system, which gives the ability to ensure reliable operation of the engine and its ventilation. Currently, many researchers focus their research interests on heat transfer and engine cooling. The article deals with the issue of heat transfer of an external cooling fan in a high voltage electric motor and the processing of the obtained information by means of neural networks. Studies have shown that the velocity at the outlet and the temperature of the internally ventilated varies depending on the load and can be predicted by neural networks. The accuracy of the simulation and simulation method is proved by calculations. The results of the study can provide an effective tool for the design of induction motors with high specific power.
Keywords: electric transport, electric motor, increase of power, cooling of electric motor, neural networks.
