Abstract[German]
Rotormagnetkern für eine induktive Stromübertragungseinrichtung für eine fremderregte Synchronmaschine, umfassend: eine Funktionsgeometrie, die einen Abstand zwischen einer am Rotormagnetkern angeordneten Sekundärspule und einem Luftspalt zwischen dem Rotormagnetkern und einem Statormagnetkern der Stromübertragungseinrichtung erhöht, sodass die Streufelder in einem Wicklungsraum des Rotormagnetkerns schwächer sind.[English]
A rotor magnetic core for an inductive power transfer device for an externally-excited synchronous machine, comprising: a functional geometry which increases a distance between a secondary coil located on the rotor magnetic core and an air gap, the air gap existing between the rotor magnetic core and a stator magnetic core of the current transfer device, so that the stray fields in a winding space of the rotor magnetic core are weaker.[French]
L'invention concerne un noyau magnétique de rotor pour un dispositif de transfert de puissance inductive pour une machine synchrone à excitation externe, comprenant : une géométrie fonctionnelle qui augmente une distance entre une bobine secondaire située sur le noyau magnétique de rotor et un entrefer, l'entrefer existant entre le noyau magnétique de rotor et un noyau magnétique de stator du dispositif de transfert de courant, de telle sorte que les champs parasites dans un espace d'enroulement du noyau magnétique de rotor sont plus faibles.
