Abstract
Description
Berührungsloser Plattentellerantrieb für Plattenspieler.Contactless turntable drive for turntables.
Beschreibung. Description.
Die Erfindung bezieht sich auf den Antrieb des Plattentellers bei Plattenspielern.The invention relates to the drive of the turntable Turntables.
Es sind bekannt: Reibrandantrieb, Riemenantrieb, Direktantrieb.The following are known: friction drive, belt drive, direct drive.
Der Antrieb gemäß meiner Erfindung, unterscheidet sich von den bekannten dadurch, daß der Antrieb des Plattentellers nicht direkt mittels Reibrand bzw. Riemen, sondern von einem zwischen getrennt gelagertem Mitnehmer und Plattenteller, mittels Dauermagneten erzeugten Magnetpolsters erfolgt.The drive according to my invention differs from the known ones in that the drive of the turntable is not done directly by means of friction belts or belts, but from a separately stored driver and turntable, by means of Permanent magnets generated magnetic pad takes place.
Durch den so erzeugten berührungsbolsen Antrieb des Plattentellers wird eine vollständige entkopplung von Antrieb zum Plattenteller erreicht.Through the contact pin drive of the turntable generated in this way a complete decoupling of the drive from the turntable is achieved.
