The paper present a novel idea of simulating a flux controller with a finite element solver embedded in the motor model for the bearingless operation of a synchronous reluctance motor. Since rotor anisotropy and strong magnetic saturation can be accurately modelled in the finite element solutions, simulating the controller with a finite element based feedback generating system gives the opportu...

Abstract: At present, because of their advantages of simple structure, low cost, low power consumption and high efficiency, single winding bearingless permanent magnet synchronous motors (SBPMSMs) have become one of the research hotspots in the bearingless technology field. However, a high motional-electromotive force (EMF) is generated by rotor rotation in the single winding, which already has...

Modeling and control of radial force in the double stator type bearingless switched reluctance motor (BLSRM) is researched. The rotational torque is controlled independently from the radial force control. And the radial force is constant which is independent from the rotor position. In order to realize steady suspension, analytical models of torque and radial force for the proposed structure ar...

Abstract A novel inverter supply for bearingless PM-synchronous motors with magnetic suspension allows the reduction of number power electronic switches. Hence, all six motional degrees freedom AC machines may be controlled via 3-phase topologies. In this paper, instead a motor consisting two half motors, one an additional radial active bearing is treated. Bearingless cylindrical rotors in cont...
