Abstract

In this paper, a novel bearingless switched reluctance motor (BLSRM) with double stator is introduced. This motor has two stators. Outside stator produces rotational torque. Inside stator generates radial force to suspend the rotor. In order to calculate the characteristics of the proposed structure, a finite element model is used. Compared with conventional BLSRM, the proposed suspension control strategy is much simpler to be implemented. From the analysis, the proposed BLSRM has linear characteristic of radial force, decoupling control between torque and radial force can be realized.
