Background: Aiming at the problems of high local temperature and uneven temperature distribution in asynchronous traction motor of high-speed Electric Multiple Unit (EMU) when it is running. Aim: In this paper, the influence of ventilation system with different structure on temperature distribution is studied. Methods: Taking 600kW asynchronous traction motor as an example, the electromagnetic-fluid-temperature analysis model of the traction motor is established, and the temperature values of different positions in the motor are obtained. The accuracy of the calculation results is verified by comparing with the actual measurement. On this basis, by adjusting the structure of stator and rotor axial ventilation holes, the relationship between temperature distribution and fluid flow state in motor is studied. In addition, the influence of fluid incidence angle on fluid velocity and heat dissipation performance of motor is also studied, and the ventilation structure scheme with relative balance of axial and circumferential temperature in motor is found out, which provides a reference strategy for the design of temperature rise of motor with forced ventilation structure. Results: The wind speed near the intake side of stator teeth and rotor teeth groove is less than that far from the intake side. The flow distribution trend of rotor vent is similar to that of stator vent, but the air in the groove is affected by centrifugal force of rotor rotation, which makes the wind speed difference on the intake side larger than that on the outlet side. The stator winding and rotor guide bar are affected by wind temperature to reach the maximum temperature at the end of the outlet respectively. The stator core is higher at the windward side and the leeward side than the other parts of the motor. The heat dissipation effect at both ends is good. The highest temperature of the stator core appears near the leeward side.

“…The water cooling structure is more safety and reliability operated in the environment of high temperature, plentiful dust and easy explosion. Shell water cooling structure for mining explosion-proof motor is a kind of ideal structure [1]- [2]. With increasing of power and decreasing of volume, the electromagnetic loads selection in the calculation of electromagnetic scheme becomes higher, which is bound to make motor heating increase.so hydraulic pressure should be increased to take the surplus heat away.…”

The well tightness of the coal mining water-cooling explosion-proof motor results in difficult heat dissipation, high hydraulic pressure is needed to increase the cooling effect. However, high hydraulic pressure may lead motor shell to deform, which makes it difficult to change the motor and maintain the motor unit. The method of adding keyhole caulk weld spots on the outer cooling water jacket was proposed to solve the problem. Based on the elasticity mechanics equations and the principle of finite element method the stresses and the deformations of the traditional and novel outer cooling water jacket were calculated separately. A hydraulic pressure experiment of the both cooling water jackets was constructed. Obviously, the stress and the deformation of the novel cooling water jacket are lower. The experimental result is consistent with the simulation results. It is effective to reduce the stress and the deformation of the cooling water jacket by adding the keyhole caulk weld spots.

“…This investigation focuses on the passive thermal design, specifically properties of the stator and rotor lamination stacks. The lamination stacks are a significant portion of the thermal pathway for removing heat from the motor [1]. The effective thermal conductivity of the lamination stack is orthotropic, as shown in Figure 2.…”

Thermal management for electric machines is important as the automotive industry continues to transition to more electrically dominant vehicle propulsion systems. With the push to reduce component size, lower costs, and reduce weight without sacrificing performance or reliability, the challenges associated with thermal management for power electronics and electric machines increase. The transition to more electrically dominant propulsion systems leads to higher-power duty cycles for electric drive systems. Thermal management of electric machines directly improves power density and reliability; however, it is a significant challenge because heat transfer and fluid flow in electric machines are complex. Thermal management is one path to improve the performance, efficiency, cost, and the sizing of electric machines to operate within thermal constraints.
