Abstract
A fault tolerant active magnetic bearing has at least three magnetically isolated control axes. To this end, the active magnetic bearing has a segmented stator which employs non-magnetic sections for magnetically isolating adjacent electromagnetic force actuators, and hence adjacent control axes. As a result, operating force actuators are not affected by magnetic poles experiencing a fault. Hence, in a three-phase active magnetic bearing rotor suspension control system, for example, full control of rotor shaft position can be maintained with only two functioning control axes.
