Abstract
A centrifugal separator includes a rotating centrifuge rotor having a casing which defines an inner separation space. A set of separation discs is provided in the inner separation space. The centrifugal separator includes a torque transmitting part connected to the centrifuge rotor. A drive motor drives the torque transmitting part for rotation of the centrifuge rotor. The drive motor has a first axial end turned towards the centrifuge rotor and a second axial end turned away from the centrifuge rotor. The centrifugal separator includes a stationary frame and a first bearing and a second bearing, which are connected to the frame. The torque transmitting part is rotatably journalled in the first bearing and the second bearing. The first bearing is provided between the drive motor and the centrifuge rotor. The second bearing is provided outside the second axial end of the drive motor.
