ABSTRACT
A synchronous generator comprising a stator and a motor
movable relative to the stator. The generator contains a
plurality of poles for generating electrical energy. The time
behavior of the voltage induced in one or several stator
windings essentially approximates the current time behavior
in one stator winding or the sum of at least several compo-
nent currents. The poles are positioned asymmetrically on
the rotor.
