A novel bearingless motor is proposed – the position of rotor and stator in switched reluctance motor is exchanged to obtain the single winding bearingless flywheel motor (SWBFM), in which the outer rotor is levitated and can directly drive the flywheel with less mechanical transmission by the combination of the levitation forces and torques. The electromagnetic characteristics are analysed by finite element analysis and the results verify the SWBFM has better torque and suspension characteristics.
