Bearings create a drag loss but can be minimised by levitating the rotor using a permanent magnet passive magnetic axial bearing. Low loss mechanical bearings or active magnetic bearing may be used as radial bearing to keep the rotor stable. A further loss may be developed in the M/G but this can be reduced by careful design choices.
