摘要：
According to the structural dimensions of the motor, a YKK450-4, 500 kW medium high-voltage asynchronous motor is taken as an example to construct the 3D mathematical model and physical model of stator and rotor radial ventilation ducts with the adjacent core segment of the high voltage asynchronous motor. Based on the theoretical knowledge of fluid mechanics and heat transfer, assumptions and boundary conditions were given to conduct calculation of the simulation, and the temperature field of the calculated region were analyzed. Finally, under the condition that the length of the ventilation channel of the stator remained unchanged, and the radial position near the shaft of the stator ventilation channel was changed, the model of ventilation dutcs was remodeled to obtain the influence of the installation position of the stator ventilation channel on the temperature field in motor. The results show that radial position of the ventilation channel affects the cooling effect of the stator windings, which provides a theoretical basis to improve the thermal dissipation performance of the motor and the optimization design of the motor ventilation structure. © 2016, Harbin University of Science and Technology Publication.
