Centrifugal separator drive unit and centrifugal separator with interchangeable drive unit

Abstract

Centrifugal separator drive unit (6) as an interchangeable drive unit of a centrifugal separator (2) comprising: - a synchronous motor (34) with a sleeve-shaped stator (20) and a rotor (33), wherein a rotatably mounted rotor (21) extends through the sleeve-shaped stator (20) as part of the rotor (33), wherein the rotor (33) comprises a rotating shaft (9) with a terminal shaft end (27) and the rotor (21) attached to the rotating shaft (9); - one or more rotating shaft bearings (17, 18) as part of the rotor (33);and- a housing unit (32) in which the synchronous motor (34) is arranged, characterized in that a cooling line (15) of a liquid cooling device (14) for cooling the stator (20), which is arranged multiple times around the stator (20), is arranged in the housing unit (32) or that the housing unit (32) is designed to provide a cooling line (15) by installing the centrifugal separator drive unit (6) in a receiving housing (7) of a centrifugal separator (6).
