Abstract
The time analysis of magnetic field in the rotor teeth of an alternator is carried out taking in account the saturation effects in the iron parts and eddy current in the rotor winding. It is supposed that magnetic field is produced by a step current impressed to the rotor slot-bar and by stator three phase sinusoidal linear distribution of current density. The method used for this investigation is the finite-element method with the state-variables approach.
