  • The SRM is more robust and lower cost than other type motors. The inverter for SRM cannot have shoot through fault, since a phase winding of SRM is independent of other phase windings. The SRM has high starting torque and high power density. But it has torque ripples due to nonlinear magnetic characteristics. Therefore, SRM has highly non-linear torque producing characteristics. Because fuzzy logic is a flexible and general-purposed method for implementing non-linear dynamic functions, it is effective for the control of high current SRM. We design the fuzzy controller and demonstrate the fuzzy control system by MATLAB.

  • The single phase switched reluctance motor(SRM) is more simpler and robust in the structure than poly phase SRM. It has the merits that it reduces the switching elements and the energy density per volume is very high. Recently, it has been researched and developed in various types and starting method due to the technique of power electronics and the computer added design. The single phase SRM is tried to apply to many industrial appliance field to substitutethe the induction motor by the single phase SRM. On the previous studies, we decided the design parameters of the single phase SRM for the blower driver to adapt the design method of the conventional machine and the poly phase SRM. In this studies, it is proposed the conditions to decide the optimal pole arcs because the stator and rotor pole arcs is very important in the characteristics of the single phase SRM. For this reason, it is analysed the characteristics of current on/off angle vs. pole arc, pole arcs vs. average torque.

  • 스위치드 릴럭턴스 전동기(Switched Reluctance Motor, 이하 SRM)은 간단한 구조와 기계적 강인성, 넓은 속도 범위를 사용할 수 있다는 장점이 있다. 하지만, SRM을 산업분야에 적용하기 위해서는 각각의 설계 변수에 따른 성능 변화에 대한 연구가 부족한 실정이며, 기기의 소형화에 대한 연구가 진행되어지고 있다. 본 논문에서는 2상 4/2극 SRM과 3상 6/4 SRM을 설계 하며, 2상 4/2극 SRM의 경우 스테퍼 회전자의 극호각과 스테퍼의 높이를 변수로 지정하여 성능을 확인하며, 3상 6/4극 SRM의 경우 2상 4/2 SRM 전동기 대비 기기의 소형화를 중점으로 설계 및 특성 해석을 수행하였다.

  • Switched Reluctance Motor(SRM) has become popular for industrial application, particularly for low medium drives due to the advantages of SRM over the other ac motors: SRM can be manufactured with low cost because it has a simple structure. But, asymmetric bridge converter that generally is used for driving requires two discrete switching devices and freewheeling diodes per phase, and cause the SRM drives to be complicated and to increase the cost of overall system. Therefore, this paper suggests a new type of 4-switch converter for SRM. 4-switch converter topology is studied to provide a possibility for the realization of low cost 3-phase SRM drive system. For effective utilization of the developed system, a new current control algorithm is designed and implemented to produce the desired dynamic performance. With the developed power conversion circuit and control scheme, it is expected that the proposed system can be widely used in commercial applications with reduced system cost.

  • Bearingless SRM(Switched Reluctance Motor) is researched for high speed or special applications which can not use mechanical bearing such as bio pump. In this paper, a novel hybrid pole bearingless SRM is presented. The proposed hybrid pole bearingless SRM has salient poles for torque and suspending force production. Motor torque is controlled by the phase currents in torque pole windings, and the suspending force is controlled by suspending currents in four suspending windings for radial direction suspension. Because the proposed bearingless SRM has divided pole structure, mutual effects between torque current and suspending current are very lower than the conventional one's. From this structure, the number of power devices for power converter can be reduced for bearingless SRM driving. The proposed hybrid pole bearing less SRM is verified by the FEM analysis and experimental results.

  • The single phase switched reluctance motor has simple, robust structure and economical drive system. So, it is useful to apply in the industrial and home applied machines. Especially, the single phase induction motor, used much in field, has a low efficiency and control ability. For the replacement of it, the single phase SRM is presented. In this paper, the design and characteristics of single phase SRM considering the rotor shape will be presented in the base of general electric motor design method and poly phase SRM design method.

  • Recently, interests for SRM have been increasing rapidly to automate the whole processes of supply chain from sourcing to procurement and improve the whole efficiency of supply chain by strategically managing the relationship with external partners (suppliers). The national procurement service of Korea is trying to build new paradigms by introducing SRM for improving the competitiveness of national public procurement service. For this, a new assessment model for evaluating and selecting suppliers with fairness and objectivity should be developed. In this paper, we propose a new SRM solution including a model that evaluates and grades of suppliers' capabilities of performing the contracts. We also explain the innovation of national public procurement system through this SRM solution.
