Characteristic Analysis of Bearingless SRM with Hybrid Stator Poles

서스펜션 포스 극을 가지는 베어링리스 SRM의 특성

In this paper a novel bearingless switched reluctance motor (BLSRM) with hybrid stator poles is proposed. The operating principle of the proposed motor is presented. Further one prototype motor is designed and manufactured. Compared with existing BLSRM, it has many advantages such as lower number of switches and cost, simpler control algorithm, lower thermal load. Meanwhile through finite element method (FEM) characteristics of the proposed structure such as inductance, torque and radial force can be obtained. According to the FEM results, the above advantages of the proposed structure can be verified.
