Abstract

Ein modifizierter Ringkern zur Verwendung in einem elektromagnetischen Bauelement ist einstückig so gestaltet, daß die Kernform an zwei Oberflächenbereichen (1,2) in der Weise von der Ringzylinderform abweicht, daß in einem ersten Bereich (1) die Ringzylinderform nach Art eines glatten Schnittes abgeplattet ist und sich in einem zweiten Bereich (2) ein podestförmiger Vorsprung mit glatter Oberfläche über die normale Ringzylinderform erhebt.

Figure 00000001
A modified toroidal core for use in an electromagnetic component is designed in one piece so that the core shape deviates from the toroidal cylinder shape on two surface areas (1, 2) in such a way that in a first region (1) the toroidal cylinder shape is flattened in the manner of a smooth cut and in a second area (2) a pedestal-shaped projection with a smooth surface rises above the normal ring cylinder shape.
