Computer-aided design of synchronous generators with comb rotors

A mathematical model of a synchronous generator with comb rotor is implemented in a computer-aided design (CAD) package. The model integrates the differential equations characteristic of an electric machine; tabled data and empirical coefficients; and geometric, electromagnetic, and economic parameters of machine design. The complexity of the model requires that the solution procedure adopt a naive random search methodology, and an expert system is integrated within the package. The expert system is used mainly for guidance, and the priority of initial parameter values is delegated to the designer. An illustrative example is described to demonstrate the methodology of the computer-aided design procedure.
