Design of novel bearingless switched reluctance motor
IET Electric Power Applications, 2012 This study presents a novel bearingless switched reluctance motor (SRM) with decoupled torque and suspending stator poles. Different from the conventional bearingless SRM, the suspending poles of the proposed bearingless SRM are separated from the phase torque poles.
