Abstract
Die Erfindung betrifft eine Spule (10) mit einem Ferritkern (16) beispielsweise zur Entstörung von in Kraftfahrzeugen verwendeten Elektromotoren. Die Erfindung schlägt vor, den Kern (16) mit einem spitzwinkligen Gewinde (18) auszubilden und die Spule (10) unmittelbar auf den Kern (16) zu wickeln, wobei eine so hohe Zugkraft auf einen die Spule (10) bildenden Draht ausgeübt wird, dass Windungen der Spule (10) reibschlüssig zwischen Flanken des Gewindes (18) gehalten sind. The invention relates to a coil (10) with a ferrite core (16), for example for interference suppression of electric motors used in motor vehicles. The invention proposes to form the core (16) with an acute-angled thread (18) and to wind the coil (10) directly onto the core (16), such a high tensile force being exerted on a wire forming the coil (10) that turns of the coil (10) are held frictionally between the flanks of the thread (18).
