  • 본 논문에서는 인덕턱스의 변화에 따른 전류 변화율을 모니터링 하여 회전자의 속도 및 위치를 추정하는 센서리스 구동방법을 제안한다. 전류의 변화율은 히스테리시스 전류제어 방법을 이용하여 인접한 두 스위치 온 타임을 비교함으로써 간단히 측정할 수 있다. 제안된 방법은 복잡한 계산이나 별도의 하드웨어를 필요치 않으므로 구현이 용이하다. 시뮬레이션과 실험 결과는 제안한 방법의 실효성을 보여준다.

  • Switched reluctance motor (SRM) drives appear today as viable alternatives to induction and brushless motor drives in a wide range of application such as machine tools, fans, and pumps. This paper deals with a new converter topology which can be used in order converter. The split source type converter consists of minimum switching devices to be used in switched reluctance motor (SRM) drive. In this proposed converter two switches and six diodes are added to split source type converter. The proposed converter has performance minimizes the negative torque, Which puts the phase current off by double impressed voltages. The major advangtage of this converter is the increase of the average output power while improving better converter efficiency in heavy load and high speed than other topologies. The proposed converter system has been implemented using 80C196KB microcontroller and experiments were carried out ot verify the simulation results.

  • This paper presents a new analytical representation and simulation of the phase inductance of a Switched Reluctance Motor(SRM) using Matlab/M-file. This simulation method has many advantages: it is free from expression, can be applied widely, demonstrates inductance profile using motor parameter only, and save run time. Moreover, this simulation method can be easily realize various SRM model unlikely the existing method that limited itself to one model. And analytical expression for inductance profile is welcome as it allows for easier analysis of the motor, for it can bring insight in it working, in formulating control strategies and in achieving high accuracy in performance computations.

  • Demand for high fuel efficiency and smart features of the vehicles, research has been intensified. Hence, research and development on electric power steering (EPS) system to replace the existing hydraulic steering system has been actively conducted. Permanent magnet motors are widely used in automotive applications due to their high power density and high efficiency. However, increasing price and limited production of rare-earth permanent magnets has recently prompted the auto parts makers to substitute permanent magnet motors by non- or less rare earth magnet motors. Switched reluctance motors SRMs), known as typical non-rare earth motors have simple structure, low manufacturing cost, and high reliability. This paper discusses design, modeling, simulation, and experimental verification of a prototype SRM drive for electric power steering system.

  • This paper deals with two kinds of novel shape switched reluctance motors (SRM) with magnetic barriers in order to improve operating performances of prototype. The magnetic barriers make rotor poles more saturated, and consequently inductance profiles are distorted. The changed inductance affects input current shape and eventually torque characteristics. In order to analyze the complicated flux pattern of the SRM with magnetic barriers and its terminal characteristics simultaneously, coupled field circuit modeling method is used. The finite element method is used to model the nonlinear magnetic field, and coupled to the circuit model of the SRM overall system. After experimental results are presented to prove the accuracy of the method, the several analysis results are compared, and the improved rotor shape is presented.

  • The switched reluctance motor(SRM) has been increasingly used in high-performance servo applications such as electric vehicles, aircraft, and direct-drive robots. The dynamic equations of SRMs are, however, highly nonlinear and this makes it difficult to control SRMs with high performance. In this paper, we propose a new robust current tracking controller for SAMs which can compensate the nonlinear characteristics of SRM(i.e., back-emf and inductance) completely and hence shows perfect tracking performance even with an arbitrary small current control loop gain. Furthermore, even in case that there exist some model uncertainties, our current controller guarantees that the stator currents can track the reference current commands with sufficiently small tracking errors. In order to justify our work, we present the tracking performance analysis and some simulation results.

  • In the conventional SRM with multi-rotor teeth, the air gap must be very small in order to drive the SRM in the saturation region that is necessary for high output torque. However, this leads to the problem of overheating; particularly in the case of a small-size SRM This paper discusses the design of a new type of SRM, namely the rolled rotor SRM. This new type does not require more than a single region of a very small airgap. This solves the overheating problem in the small size SRM. Moreover, the use of the rolled rotor, instead of the conventional toothed rotor, grades the airgap region in a fashion that gives a smooth variation in the reluctance and smooth shapes of both current and torque. The latter functional behavior is required in many applications such as servo applications. The paper first addresses general design steps of the rolled rotor SRM then proceeds to the simulation results of the new SRM in order to evaluate the advantages gained from the new design. In addition, this paper compares the torque ripples obtained from the new design to its equivalent conventional one.
