Abstract

Pumpe mit Elektromotor, insbesondere für ein Kraftfahrzeug, zum Fördern eines Fluides, umfassend ein Laufrad mit Förderelementen, von dem um eine Rotationsachse eine Rotationsbewegung ausführbar ist, einen an dem Laufrad (18) vorhandenen Arbeitsraum, einen Elektromotor mit einem Stator und einem Rotor (16), wobei der Rotor (16) mit Permanentmagneten (17) versehen ist, ein Gehäuse (8), wobei das Laufrad (18) mit den Förderelementen und der Elektromotor innerhalb des Gehäuses angeordnet sind und vorzugsweise die Pumpe in den Elektromotor integriert ist oder umgekehrt, indem der Rotor (16) von dem Laufrad (18) gebildet ist, wobei die Permanentmagnete (17) an dem Rotor (16) vollständig von einer Kapselung (31) fluiddicht umschlossen sind und/oder die Permanentmagnete (17) aus einem kraftstoffbeständigem Material, z. B. SmCo, aufgebaut sind.
