| 摘要 |
The invention refers to a centrifugal separator for centrifuging components contained in a liquid mixture and having different density. A rotating centrifuge rotor is arranged to rotate around a centre axis and comprises a casing defining an inner separation space. An inlet channel is provided for supply of the liquid mixture of components to be separated to the separation space. At least one outlet channel is connected to the separation space and provided for discharge of a component separated during operation. A torque transmitting part around the centre axis is fixedly connected to the centrifuge rotor. A drive motor drives the torque transmitting part and thus the centrifuge rotor in such a way that the centrifuge rotor is brought to rotate. The drive motor comprises a stator and a rotor, which is fixedly connected to the torque transmitting part. The rotor of the drive motor surrounds a cavity which is through-flown by liquid during operation. The drive motor is provided axially outside the centrifuge rotor.
