Abstract

The present disclosure provides a centrifugal separator (1) for cleaning gas containing contaminants. The centrifugal separator (1) comprises a stationary casing (2), enclosing a separation space (3) through which a gas flow is permitted, a gas inlet (17) extending through the stationary casing (2) and permitting supply of the gas to be cleaned, a rotating member (7) comprising a plurality of separation members arranged in said separation space (3) and being arranged to rotate around an axis (X) of rotation, a gas outlet (30) configured to permit discharge of cleaned gas and comprising an outlet opening through a wall (6) of the stationary casing (2), a drainage outlet (29) configured to permit discharge of liquid impurities separated from the gas to be cleaned and an electrical motor (23), for rotating the rotating member (7). The centrifugal separator (1) further comprises a control unit (28) which is configured to control the operation of the electrical motor (23) and to drive the electrical motor (23) in at least two different operational modes and to further switch between operational modes depending at least on information of at least one measured internal parameter of the electrical motor (23).
