Modelling and fast calculating the characteristics of synchronous machines with the finite element method

Analytic motor calculation tools need less time than numeric programs, whereas considering geometric details is easier by using numeric ones. Thus, it is proposed to combine both technologies. To decrease the calculation time, most possible parts should be calculated analytically and only a few numerically. In this paper, a method to figure out a ldquofundamental wave modelrdquo of salient pole synchronous machines within a short time by using FEM technologies is shown. This model can be used for further calculations with analytic programs. The presented method uses a simplification to be faster than exact simulations, but nevertheless it yields excellent results.
