Abstract :
Bearingless switched reluctance motors, which can control rotor radial positions with magnetic force, have been proposed. Bearingless switched reluctance motors have combined characteristics of switched reluctance motors and magnetic bearings. In this paper, a method of determining advanced angle of square-wave currents in bearingless switched reluctance motors is proposed. Under every torque condition from no load to full load, the stable operation is realized by opportunely determining the advanced angle of square-wave currents with the proposed method. It is shown in experimental results that the proposed method is effective for stable operation
