The simulation of electrical machines is done in several steps. First the construction is to be done using the
bottom up or top down method resulting in a model consisting ponents, volumes, areas, lines and
points with different properties according air, steel, aluminium or copper. Within the second step the
meshing is done respecting areas with high ic work such as the airgap with very small Finite
Elements. After finishing the model with border conditions and loads within the third step the user may
analyze his problem. Following this way the user can do static and harmonic calculations in a short time, a
user friendly menu is helpful.
The problem of those Finite Element simulations is the impossibility to simply change parameters such as
airgap distance, machine diameter or yoke thickness. On the other hand motion of machines, that is the
moving of the rotor within or towards the stator according, or the changing voltages or currents at the
windings is impossible. To do those ic simulations the engineer needs a Finite Element
System with macro language and changeable parameters, ical elements such as voltage or
current sources, resistors, inductances and coils to switch the elements of t
