Abstract :
An original type of magnetic suspension, which is compact and well adapted to high speed rotation is discussed. This suspension is based on a permanent radial bearing, which allows radial and angular stability simultaneously. Axial stability is reached thanks to a unidirectional active axial bearing. This suspension operates with a plane air gap and is well adapted to the levitation of flat rotors
