Abstract
A system for supporting a rotor without contact with a stator comprising a magnetic bearing apparatus mounted on the stator and including a controlling magnet means fixed to the stator, a non-controlling magnetic pole fixed to the stator, a biasing magnetic poles sandwiched between the controlling magnet and the non-controlling magnetic pole, and a rotor magnetic pole fixed to the rotor to enable the magnetic path of a biasing flux to run in a plane which includes the longitudinal axis of the stator. The non-controlling and rotor magnetic poles may have teeth facing each other.
