Abstract
In this paper, a novel structure Bearingless SRM with hybrid stator poles is proposed. The motor torque can be controlled independently from radial force control. Analytical models of torque and radial force for proposed structure are explained. Based on these models, control scheme of desired radial force is proposed. In this control method, the magnitude of force can be controlled in arbitrary direction and magnitude by selecting some combinations of radial force windings. The validities of structure and control method are verified by the experimental results when motor is at standstill and running.
