摘要：

This article presents a method to determine the convective heat transfer coefficient on the end windings of an induction motor. Based on dimensional analysis and heat transfer coefficient values derived by computational fluid dynamics, a correlation between given boundary conditions and the heat transfer coefficient on the end windings has been found. The results can be used in transient simulations of operating cycles. In order to make the application more universal, the approach has been made independent of the characteristics of the fan used for cooling the electrical machine.
