Abstract
A combined analytical-numerical calculation of electrical machines is dealt with. Analytical motor calculation tools need less time than numerical programs whereas considering geometric details or non-linear material properties is easier by using numerical methods. 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 addition, the numerical calculation should run without time-consuming user interaction. Therefore the construction of FEM-models of arbitrary electric machines is automated. Furthermore a method is implemented to identify the parameters of a fundamental-wave model of salient pole synchronous machines within a short time by using FEM technologies. This model can be used for further calculations with analytical programs. The characteristic field factors of salient pole synchronous machines are also calculated numerically, as their analytical calculation leads to dissatifactory results. As an outlook for further research, two different approaches to calculate the transient reactances of synchronous machines are presented, as their analytical calculation is not reliable.
