Abstract

Der elektrische Antriebsmotor für eine Kreiselpumpe für insbesondere Heizungsanlagen umfasst ein Spaltrohr (1) und eine darin in wenigstens einem vorderen Lageraufbau abgestützte Antriebswelle (10) mit einem Rotor (11). Der vordere Lageraufbau (5) weist ein stationäres Lagerteil (6) und ein rotierendes Axiallagerteil (7) auf, wobei letzteres an dem Radiallagerteil axial anliegt und mit der Antriebswelle (10) drehfest verbunden ist. Ferner sind in Nähe des vorderen Lageraufbaus (5) ein Raumtrennungsmittel (17) und eine Axialbohrung (13) in der Antriebswelle (10) vorgesehen, um zu erreichen, dass zur Schonung insbesondere des Rotors (11) ein kurzer, nach außerhalb des Spaltrohres (1) zurückführender Strömungsweg (13, 18, 20) für einen Förderflüssigkeitsanteil vorgesehen ist, der über den Lagerspalt (19) des vorderen Lageraufbaus (5) in das Spaltrohr eindringt (Fig.1).
