A platform-independent software for the design and analysis of windings of rotating electrical machines

In this paper the Authors present a highly modular and platform-independent software, being based on the MATLAB® programming environment, which is proposed as a valuable aid in the design and analysis of the windings of rotating electrical machines. Unlike the major part of the commercial software, the cases of both symmetric and asymmetric (unbalanced) windings with any number of phases are here considered. The software can perform a considerable amount of calculations in order to determine automatically the optimal structure of the winding starting from its specifications. It is also able to draw the winding map and gives the results of calculation for the harmonic winding factors. The realized software allow the designer to reduce the harmonics winding coefficient with the only drawback of a small reduction of the fundamental coefficient, both for e.m.f. and m.m.f.
