Abstract

Elektromagnetische Drehantriebseinrichtung (10) mit einem Stator, der Elektromagneteinrichtungen aufweist, die mit einem Rotor (11), der mit zumindest einem Permanentmagneten (13) ausgebildet ist, zu dessen Drehung ebenso wie zu dessen elektromagnetischer Lagerung zusammenarbeiten, und mit einer Steuerbzw. Regeleinrichtung (20) für die elektromagnetische Lagerung und Drehung des Rotors (11), wobei der Stator in Form von Segmenten (14) mit einer Erstreckung (19) nur über ein Teil eines durch den Rotor (11) definierten geometrischen Kreisumfangs ausgebildet ist, wobei im Betrieb durch die den Elektromagneteinrichtungen (15, 21) der Segmente (14) des Stators zugeführten Ströme in zur Oberfläche des Rotors (11) tangentialer sowie normaler Richtung Kraftkomponenten (3a, 3b) gebildet werden, die ein Drehmoment sowie zwei Tragkräfte in unterschiedlichen radialen Richtungen senkrecht zur Rotor-Drehachse (7) herbeiführen.
