Consideration on new theoretical solutions of special electric machines using specialized soft of electromagnetic field numerical analysis

摘要

Special electric machines have a large field of application and actual requirements for electromechanical systems clam new and very performing solutions. There are a lot of papers on this subject, but anytime is mandatory to do something else to help users to develop high level systems. Main intention of the authors for this paper is to present a modality to analyze and to design a new solution of electric machine only trough finite element method. Actually, the users are asking for very performing electric machines, having high density torque that means to develop as higher as possible torque in a relative small volume, relative to the usual electric machines. To design such electric machines there is only one way - to use numerical methods based on finite element method. The most part of specialists that present these aspects are working in the field of special electrical machines since more than 30 years, developing many solutions and designs for high performances special electric machines.
