The bearingless flux switching slice drive is a recently introduced motor topology in the field of bearingless drives. It combines the magnetic rotor suspension of bearingless slice drives with the torque generation of flux-switching motors. Due to the lack of magnets embedded in the rotor, the topology offers advantages in applications with disposable rotors and high temperature working conditions. This paper describes the general working principle and control of both bearing force and motor torque. A prototype was built and the control was implemented on a TI DSP. The control was built using the X2C toobox. This toolbox enables developers to generate the DSP code from a Simulink or Xcos-Scilab control model.
