Provided is an electric stabiliser for stabilising a floating structure that includes a track for guiding a mover as a moving stabiliser mass. A direct current (DC) linear motor includes a planar stator that extends along the track and the mover that is adapted to move forwards and backwards along the track as the stabiliser mass. The planar stator includes a polyphase stator winding with winding coils connected. The mover includes permanent motor magnets facing the polyphase stator winding that define mover poles of alternating polarity along the track direction. Two active magnetic bearings is positioned between the track and a main body of the mover for selectively levitating the mover. In use, the active magnetic bearings levitate the mover above the track and the DC linear motor is controlled to move the mover backwards and forwards along the track to dampen a rolling/pitching movement of the floating structure.
