Abstract
The paper presents analytical and experimental determination of the forced convection heat transfer coefficients over the flat side of a permanent magnet synchronous generator coil. In the analytical part, the forced convection coefficients at different wind speeds are calculated based on various known equations of the forced convection heat transfer coefficient with unhealed starting length. The experimental part consists of loading the coil with DC current and measurements of the coil temperatures with thermal sensors while it was inside a wind tunnel. Based on the measurement, the convection coefficients were found. In the final part, the experimental and analytical results are compared. It is shown that the accuracy of the analytical results is more precise in high turbulent flows.
