摘要

This article reports a detailed finite element analysis for thermal characterization of switched reluctance motors (SRM). Prediction of steady-state and transient thermal characteristics of SRM is presented. The convection coefficient at different heat dissipating walls inside SRM, which is not a material property, but a quantity that solely depends on the air velocity at the respective walls, is the major parameter to be evaluated carefully for an accurate simulation of heat distribution. A computational fluid dynamics (CFD) procedure is implemented for the first time on SRM for this purpose. The basic equations, various steps to be followed during three dimensional finite element thermal analysis, and the results of simulations are presented.
