Abstract

In Hydraulikantrieben werden kompakte, leistungsfähige Motor-Pumpen-Aggregate benötigt. Diese Forderungen werden dadurch erreicht,dass ein Elektromotor und eine oder mehrere Pumpen so weit wie möglich in einem Gerät integriert werden. Das weist allerdings den Nachteil auf, dass somit nur ein spezieller Typ einer Pumpe in den Motor integriert werden kann. Bei dem erfindungsgemäßen Elektromotor können auf einfache Weise unterschiedlichste Typen von Pumpen an den Elektromotor angebunden werden, ohne die Vorteile herkömmlicher Aggregate, nämlich die inhärente Flüssigkeitskühlung und -schmierung des Elektromotors, zu verlieren, da bei dem vorliegenden Elektromotor der Mantel des Motorgehäuses zur Aufnahme einer Kühlflüssigkeit zumindest teilweise hohl ausgebildet ist und in den Lagerschildern zumindest jeweils ein Verbindungskanal für die Zufuhr von Kühlflüssigkeit vom Mantelhohlraum zu den Lagern vorgesehen ist.
