Blow-by gas filtration assembly

A blow-by gas filtration assembly fluidly connectable to a crankcase ventilation circuit of an internal combustion engine to receive blow-by gases and filter suspended particles contained in the blow-by gases, wherein the filtration assembly has an axis and comprises:

• a filter group which extends along the axis and has a hollow cylindrical shape comprising a central cavity configured for being crossed by blow-by gases radially;
• a control group that supports and rotates the filter group comprising:
• i) a hollow shaft extending along the axis at least partially inside the filter group to which the hollow shaft is operatively connected, defining an inner duct fluidly connected with the central cavity for circulation of the blow-by gases;
• ii) an electric motor comprising a stator and a hollow rotor, wherein the hollow rotor is operatively connected to the hollow shaft positioned thereon, to receive an electromagnetic control action from the stator and command in rotation the hollow shaft and thus the filter group.
