A tool to help to design windings of permanent magnet synchronous machines

This paper deals with the design of winding of permanent-magnet (PM) synchronous machines. One of the major issues is to develop a tool which can generate balanced winding solutions according to designer´s criteria and to qualify them by computing the winding factor, magnetomotive force harmonic content and the electromagnetic parameters of the PM machine. The tool includes also an analytical model to compute accurately no-load flux, electromotive forces, inductance parameters and electromagnetic torque under defined loads. The capabilities of the tool, its basic principles, some examples and validations with Finite Elements Analyses (FEA) will be presented.
