Abstract
- In this paper, a new type 12/14 bearingless switched reluctance motor with double windings is presented. The stator includes two types of poles such as suspending pole and torque pole. Different from the previous 8/10 structure, double windings including bias winding and control winding are installed on the same suspending pole. In addition, in order to reduce the coupling between torque and levitation force, the stator torque poles are shifted with one angle. Windings of two adjacent torque poles are connected in series. Therefore in order to explain advantages of proposed motor, structure and basic operating principle are introduced. In the meanwhile, levitation force is derived by means of equivalent magnetic circuit. The force characteristics with respect to current and displacement are analysed. In addition, by means of finite element analysis, coupling characteristic and selfâstarting characteristic are investigated. The validity of the structure is verified by the analysis and experimental results. [ABSTRACT FROM AUTHOR]
