Bearingless switched reluctance motor (BSRM) has the advantages of high integration and low loss, and is especially suitable for flywheel batteries. In order to enhance the reliability and fault tolerance ability of BSRM, a novel dual-channel BSRM is proposed in this paper. This motor has the combined merits of switched reluctance motor and magnetic bearing, and can realize dual-channel faulttolerant operation. The scalloped rotor poles are evenly distributed on the inner and outer walls of the rotor. All rotor poles are specially widened, which is benefit for raising the continuity of radial suspension force. Through the dual-phase-conduction decoupling control rules, the electromagnetic torque and suspension force can be generated simultaneously without serious coupling problem. The basic topology, operation principle, control method, and electromagnetic characteristics are analyzed. Field-circuit coupling joint simulation results of Simplorer and Maxwell confirm the feasibility of the proposed novel motor and the validity of decoupling control method.

“…Therefore, the effect of short-circuit current should be considered when the levitation force is compensated. As described in [17], the expression of short-circuit current is obtained as ( ) Fig. 3 shows the calculated results and FE results of the short-circuit current when the winding A1 is short and where i a2 =9A, i a3 =9A and i a4 =3A.…”

Due to all winding currents are controlled independently, the fault-tolerant control of single-winding bearingless switched reluctance motor (SWBSRM) is more flexible. In this paper, a compensation strategy for short-circuit fault in SWBSRM is investigated to improve the reliability of BSRM. Firstly, the mathematical model with compensation for short-circuit fault is established with consideration of two-phase coupling. Secondly, the validity of the proposed model is verified by the finite element method (FEM). Then a compensation strategy based on this model is proposed to realize rotor levitation in short-circuit fault mode. Finally, the proposed strategy is verified by simulation.
