Abstract

Der Antrieb weist einen Stator (11) und einen Rotor (12) auf. Der Rotor enthält eine Umfassung (14), die einen von dem Stator (11) abstehenden Steg (26) umgreift. Permanentmagnete (18, 19, 20) des Rotors wirken mit Elektromagneten (28, 29, 30) des Stators (11) zusammen, um den Pumpenantrieb zu bewirken und gleichzeitig eine Magnetlagerung zu bilden.
