Modeling and control design simulations of a linear flux-switching permanent-magnet-levitated motor
Mechanical Engineering Journal, 2017 For flux-switching PM (FSPM) motors, permanent magnets (PMs) are placed in the stator and not in the rotor structure as in the majority of PM motor designs. Recently, FSPM bearingless motors have been developed for special applications.
