Bearingless switched reluctance motors (BSRM) obtain great attention in the domain of high-speed motor. This paper points out the significance of the research and analyzes the main principle of BSRM. The development of BSRM's mathematic model is described in detail. For BSRM~s magnetic . field, the finite element analysis (FEA) is done considering the rotor displacement or not and the FEA results prove the validity of BSRM's mathematic model. The paper introduces the factual BSRM experiment under no load and full load. For the nonlinear, muhivariable and severely coupled BSRM system, some advanced decoupling control algorithms are used. The simulation results show the feasibility of these control algorithms.
