Abstract

Es wird im Folgenden eine Vorrichtung beschrieben, die gemäß einem Ausführungsbeispiel einen Träger, der entlang einer Längsachse eine durchgehende Öffnung aufweist, sowie mindestens ein um den Träger zu einem Ringbandkern gewickeltes weichmagnetisches Band aufweist. Das Band ist dabei direkt auf den Träger gewickelt, sodass zwischen dem Ringbandkern und dem Träger kein Spiel vorhanden ist. Der Träger kann folglich als Teil des Gehäuses des Ringbandkerns dienen.A device is described below which, according to one embodiment, has a carrier which has a continuous opening along a longitudinal axis and at least one soft magnetic strip wound around the carrier to form a toroidal core. The strip is wound directly onto the carrier so that there is no play between the toroidal core and the carrier. The carrier can therefore serve as part of the housing of the toroidal core.
