Abstract

In order to fix the problems for high speed EMU that non-uniform temperature rise exist in axial and circumferential directions of asynchronous traction motor. We establish three dimensional solid models to analyze electromagnetic and fluid solid coupling filed of motor. And we make the comparison between numerical results of finite elements and experimental results. Based on that, we adjust circumferential distribution form and structure of axial vent of stator and rotor to research the relationship between the changes of key components inside the motor and temperature rise. By adjusting the incidence angle of fluid, we analysis the effect of fluid velocity to thermal performance of the motor. Through the above research we find the ventilation structure program which has balanced temperature distribution of axial and circumferential within the motor. And provide a reference strategy of temperature rise design of forced ventilation motor.
