This paper presents a thermal study to define the appropriate correlations allowing the determination of the convective heat transfer coefficient overlarge parallel rectangular fins for a permanent magnet synchronous generator coil. For this purpose, an experimental setup is developed for both horizontal and vertical orientations and different input currents. The experimental results are compared...
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...
This paper presents the analytical thermal analysis of a permanent magnet generator stator coil. The analytical analysis consists of a lump parameter thermal network (LPTN) to predict the steady state and transient temperature of the coil module. In the steady state part the average temperature of different parts of the network are estimated by using the matrix inversion and an iterative loop. In...
This paper presents a review of the losses and thermal analysis of permanent magnet assisted synchronous reluctance motors. Various types of solutions for critical parts of heat extractions and different empirical correlation for determination of each part are presented in details. Finally the experimental methods for determination of the critical parameters are presented. In this paper has tried...
This paper presents analytical and numerical thermal analysis of three different toroidal coils levitated on an aluminum plate. The analytical method consists of a network of thermal resistances that make it possible to estimate the average temperature of the coils. In the numerical method, by using the FEM thermal and magnetic analysis, the average temperature of the coils and the amount of the in-rush...
