(EN) METHOD FOR PRODUCING AN ELECTROMAGNETIC ACTUATOR, AND ELECTROMAGNETIC ACTUATOR
(FR) PROCEDE DE FABRICATION D'UN ACTIONNEUR ELECTROMAGNETIQUE ET ACTIONNEUR ELECTROMAGNETIQUE AINSI OBTENU
Abstract
(DE) Es wird ein Verfahren zur Herstellung eines elektromagnetischen Aktuators beschrieben, wie er z. B. zum Antrieb eines Ventils eines Verbrennungsmotors benutzt wird. Um die durch Durchbiegungen der Joche (1a, 2a) der Elektromagnete und/oder des Ankers bei Aktuatorbetätigung in den Endstellungen des Ankers (5) auftretende Luftspalte wenigstens weitgehend zu kompensieren, werden diese ermittelt und durch eine entsprechende Profilgebung der Joche und/oder des Ankers ausgeglichen.
(EN) Disclosed is a method for producing an electromagnetic actuator which can, for example, be used to drive the valve of an internal combustion engine. In order to compensate at least extensively for air-gaps caused by deflections in the yoke (1a,2a) of the electromagnets and/or the rotor when the actuator is actuated in the final positions of the rotor (5), said air-gaps are determined and compensated by means of a corresponding profile which is conferred upon the yokes and/or rotor.
(FR) Procédé de fabrication d'un actionneur électromagnétique, utilisé par ex. pour l'entraînement d'une soupape d'un moteur à combustion interne. Pour compenser au moins en grande partie les discontinuités magnétiques apparaissant en raison des flexions des culasses (1a, 2a) des électro-aimants et/ou de l'induit en cas d'actionnement de l'actionneur dans les positions terminales de l'induit, lesdites discontinuités sont déterminées et compensées par le fait qu'un profil correspondant est conféré aux culasses et/ou à l'induit.
