Abstract (en)

[origin: WO0022719A1] An electric machine, especially a three-phase generator, with an exciter (26) in the form of a claw-pole machine that delivers a required exciting current for a generator. The exciter is arranged to the side of the generator and its dimensions are substantially smaller than those of the latter. Permanent magnets (39) are arranged close to the claws (28,29) of the stator (28,29) facing the armature (32) of the exciter in a magnetic dispersion area in between said claws, thereby enabling undesirable stray fields to be terminated.
