Optimizing of cooling in electric machines

This paper deals with thermal optimization of electric machines. There are described the connections of finite element methods with optimizations algorithms. This connection is used for modifications of brushless motor construction. Solution of physical field model is realized by FEMM program which cooperate with optimizing program. Optimizing program was created in Java programming language. This program can be easily modified for various Finite Elements Methods solvers. Cooperation between optimizing program and FEMM is realized be LUA script. Four optimizing algorithms were chosen for using in program: Random find, Bees method, Hill climbing and Simulated annealing. Compare of these methods is in this paper. The part of this work is the complete thermal analysis of AC machine and modifications of cooling
