Abstract
A gas separator for removing contaminants from a crankcase gas which is produced during operation of an internal combustion engine includes a centrifugal rotor with a plurality of separation discs for separating the contaminants from the crankcase gas, the centrifugal rotor being arranged inside a stationary rotor housing having a gas inlet for conducting crankcase gas to the centrifugal rotor and a gas outlet for discharging the cleaned crankcase gas from the centrifugal rotor, and an electric motor which is arranged for rotation of the centrifugal rotor about a rotational axis, and A gear device is arranged between the electric motor and the centrifugal rotor, the gear device having a gear ratio arranged to increase the rotational speed of the centrifugal rotor in relation to the electric motor.
