Obersieht: Klauenpolgeneratoren The alternator is modelled by finite elements, and the 3dimensional static magnetic field is calculated taking the saturation into account. To determine the points of operation, the phasor diagram of the fundamentals of current and voltage is developed out of new inductivity functions. From these inductivities the voltage equations of the machine can be derived and a simulation of the waveforms of current and voltage can be carried out for any given load.
