Analysis of the operating principle of a dual-armature consequent-pole bearingless flux reversal permanent magnet machine

This paper proposes a new type of dual-armature alternating pole bearingless magnetic flux reverse permanent magnet machine, which combines the advantages structure and structure. machine shows high torque density good fault tolerance, can not only reduce number magnets but also further improve machine’s torque. It is suitable for use in wind power, aerospace, other applications. The used to performance suspension force. Based on by adding an additional set stator teeth suspended windings, obtained. halved, each has same polarity. ferromagnetic piece next automatically acts as pole. introduction its related structure, flux, rotor back electromotive force, cogging torque, electromagnetic etc., are analyzed. higher conferring output capacity low ripple.
