Abstract:
1. A centrifugal separator comprising a stationary part forming a base configured to be located on a ground, a non-rotating part, which is elastically connected to the stationary part by means of an elastic connection, a rotating part, which is configured to rotate around an axis of rotation and comprises a centrifuge rotor, which comprises a rotor casing forming an inner separation space, and a rotating bearing-receiving element, wherein the centrifuge rotor comprises a disk package having a plurality of separating disks and wherein the rotating part is journalled in a stiff manner in the non-rotating part in such a way that the rotating part and the non-rotating part form a common pivot unit that is in pivotable communication with the stationary part by means of the elastic connection, a drive arrangement for driving the rotating part to rotate around the axis of rotation within a range of revolutions, which is from zero to a highest number of revolutions per minute and which comprises at least an operating number of revolutions, the drive arrangement comprising an electric motor, the electric motor comprising a rotor and a stator, the rotor being coupled to the rotating part and the stator being comprised of the non-rotating part, an inlet channel, which extends into the inner separation space for feeding of a medium to be separated, at least an outlet channel, which extends out from the inner separation space for discharge of a separated product, the bearing-receiving element being tubular and at least one of the inlet channel and the outlet channel extends through the bearing-receiving element.
