A method for operating an active oil separator for separating oil from exhaust air of a crankcase of a motor vehicle with an internal combustion engine. An engine operating state of the internal combustion engine is detected. A first SET rotational speed of the oil separator is determined as a function of the detected engine operating state and a first characteristic map. A maximum SET rotational speed of the oil separator is determined as a function of the first SET rotational speed by the determination device. A preferred SET rotational speed is determined on the basis of the maximum SET rotational speed by a determination device. An electric motor is controlled to drive the oil separator at the preferred SET rotational speed by a control device. A device is also provided for separating oil from exhaust air of a crankcase of a motor vehicle with an internal combustion engine.

A centrifugal separator for cleaning gas containing contaminants includes a stationary casing enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas to be cleaned, a rotating member including a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation, a gas outlet configured to permit discharge of cleaned gas and including an outlet opening through a wall of the stationary casing, a drainage outlet configured to permit discharge of liquid impurities separated from the gas to be cleaned and an electrical motor for rotating the rotating member. The centrifugal separator further includes a control unit configured to control the operation of the electrical motor and to drive the electrical motor 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.

Embodiments for a portable and compact centrifugation and thermal management system capable of separating and transporting biological samples while maintaining sample quality for periods of shipment time are described. A compact, automatic centrifuge holding exactly one sample tube is inside an insulating and thermally managed container suitable for standard shipping. A rotor to retain a sample tube is pre-balanced. An electronic controller starts, times and stops centrifugation automatically, responsive to placement of a lid. Thermal management may comprise a phase change material. Embodiments are free of user controls. Embodiments are free of the need for external power or external control.
