POLE GENERATOR WITH VIBRATION DAMPING

Disclosed is an electric machine, comprising a rotor (10), especially a claw pole rotor. Said rotor (10) includes an exciter system which is made up of electrically excited individual poles arranged inside said rotor (10), said poles consisting of electromagnetically excited poles (28) and counter poles (34).A pole gap closure (55) is inserted between the poles (28) and counter poles (34) which are alternately placed on the periphery of the rotor (10), at least partially filling the free areas thereof. The pole gap closure (55) is characterized in that it is supported at the roots of the poles (36;31) by at least one of its axial end areas (61) below projecting elements (64). Se propone una maquina electrica con un rotor (10) especialmente un rotor de polo de garra. El rotor (10) presenta un sistema excitador formado de polos individuales excitados electricamente en el rotor (10) en forma de polos (28) y contrapolos (34) excitados electromagneticamente. Un cierre de huecos de polo (55) esta colocado entre los polos (28) y los contrapolos (34) alternantes en la periferia del rotor (10) , cierre que cuando menos parcialmente llena los espacios libres. El cierre de huecos de polo (55) esta caracterizado porque este se apoya con cuando menos una de sus zonas extremas axiales (61) por medio de sobresalientes (64) en las raices de polo (37, 31) Figura 3.
