MADES Tool for the Analysis and Design of Electrical Machines

Abstract

In this paper, a numerical tool is presented in the field of the computation of electrical unknown of an electrical machine, very suitable to solve non-symmetrical condition too by means of a very friendly computer evaluation. This software tool, written in MATLAB language, bases itself on a formulation of air-gap field distribution by means of the linear combinations of the most elementary components of m.m.f (in case of windings) or of flux density (in case of permanent magnets) called Window functions. Differently from the standard methods, that allow appreciable results only after laborious calculations and complicate mathematical approaches that consent to formulate the problem in convenient domain, the proposed technique approaches and solves any problem directly in the time domain. The other most important feature of this procedure is its easy implementation into a proper tool that allows a friendly utilisation both by non expert people and by specialists in design phase activity or during the computation of performances in transient operations or in test conditions. In the paper, this tool is proposed in order to solve three cases of electrical machines simulations: the results demonstrate the interesting performance of the proposed tool.
