Determination of Critical Parameters in Electrical Machine Thermal Models
TL;DR: In this paper, the authors discussed the problem concerning the determination of some thermal parameters which are very complex to compute, such as the equivalent thermal resistance between external frame and ambient, equivalent thermal conductivity between winding and lamination, forced convection heat transfer coefficient between end winding and end-caps, radiation heat transfer ratio between external frames and ambient and interface gap between lamination and external frame, air cooling speed, and the bearings effective thermal resistance.

Heat sinks with sloped plate fins in natural and forced convection
Gustavo A. Ledezma,Adrian Bejan +1 more
TL;DR: In this article, an experimental and numerical study of natural convection and forced convection air cooling of plate finned heat sinks is presented. And the results based on complete three-dimensional numerical simulations of the flow and heat transfer confirm the validity of the results determined based on direct measurements.
