Effect of Ventilation Systems on Stator Thermal Field of Induction Machines

Article Preview

Abstract:

A three dimensional physical model for coupling calculation of flow and thermal transmission in induction machine is established in order to research the effect of stator ventilation on the performance of radiating with the method of finite volume element. The thermal fields of different ventilation structures under same basic size and equal total ventilation quantity of the induction machine are calculated and compared numerically. The results indicate that the addition of wind path will reduce the highest temperature in stator and cool the overhang portion remarkably.
