Three axis active magnetic levitation for inertial sensing systems

The invention relates to an inertial sensor based on the magnetic levitation of an inertial mass comprising an active magnetic bearing unit arranged in such a way as to levitate the inertial mass and characterized by the fact that it furthermore comprises additional active magnetic bearings units arranged in such a way as :- to control the position of said inertial mass along three independent axis. - to create, for any of said independent axis, restoring forces that can be oriented in any of the two directions of said independent axis.
