Расчетно-экспериментальное тестирование программы FEMM и преодоление проблем её использования для расчета магнитного поля электрических машин

Abstract

General capabilities and problems of application of FEMM (Finite Element Method Magnetics) program located at http://femm.berlios.de are analyzed. The program testing is con-ducted using an electrical machine of elaborate design by means of analytical and experimental data comparison. A practical way of overcoming of one of the magnetic field computation problems revealed is suggested, which consists in taking into consideration dissimilar axial lengths of electrical machine core sections
