  • This paper deals with dynamic analysis of linear switched reluctance motor considering electromagnetic characteristics. First, inductance profile of linear switched reluctance motor calculate at align and unalign position and phase resistance using analytical method. Analytical method of this paper used space harmonics method, also, analysis result compares with data that is derived through an finite element method, and proved validity. In dynamic simulation of linear switched reluctance, we analyzed dynamic characteristic of linear switched reluctance motor according to single pulse waveform and hard chopping voltage PWM.

  • Inherent speed-torque performance of Switched Reluctance Motor is similar to that of series wound DC motor. Thus, the speed of the motor is extremely regulated according to load torque. For the purpose of controlling the speed and torque of SRM it is necessary to change the applied DC link voltage or the switch-ON and switch-OFF angles which control the phase current of the motor. This paper describes speed-torque characteristics of an integral horse power Switched Reluctance Motor by adjusting the switch-ON and switch-OFF angles. Speed at rated load torque can be regulated by adjusting the switching angles and the control scheme is applied to 2kW, 3 phase, 6/4 SRM.

  • The Switched Reluctance Motor is an electric machine in which torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximized. The main advantages of this motor lie in the simple robust construction and low manufacturing cost. In this paper, we describe the design features of single-phase switched reluctance motor for low-power variable-speed drives.

  • A high speed, three phase, 12/8 pole, 225 kW switched reluctance motor (SRM) has been designed and analyzed. A circuital approach has been used to find the geometry, windings parameters and electromagnetic loading. Then, the 3D finite element method (FEM) has been used to calculate the static torque more accurately and optimize the design. The efficiency of the designed SRM is almost constant over wide range of speed and its phase current is less sensitive to the speed than that of an induction motor of the same rating. Recommendations for manufacturers and users are given.

  • A design and analysis program is proposed for switched reluctance motor using an analytical method and a CAD program LabVIEW. The algorithm uses conventional permeance method, in which flux linkages, inductances and torques are calculated numerically. In order to analyze a dynamic characteristics of the motor, voltage control scheme is fallen and a single pulse operation is applied. 2 SRM models are analyzed under the given specifications and constraints. The results compared with measured data.

  • Novel 8/10 bearingless switched reluctance motor, which can control rotor radial positions with magnetic force, is proposed. The motor has combined characteristics of switched reluctance motor and magnetic bearing. This paper proposes a air-gap control system method of suspending force control in a bearingless switched reluctance motor (BLSRM). The proposed radial force control scheme is independent to the torque winding current. A PI direct current control (DCC) controller and look-up table are used to maintain a constant rotor air-gap. From the analysis and the experimental results, it is shown that the proposed strategy is effective in realizing a naturally decoupled radial force control of BLSRM.

  • A switched reluctance motor (SRM) has very simple structure and robustness. Generally, for driving SRM, several (6-8) switching devices are required. This is weakpoint for reducing the cost of SRM drive. In This paper, we simulate the single phase and three phase SRM, and we compare the performance or single phase SRM with that of three phase SRM through experiment. Finally we suggest the appropriate application of single phase SRM.

  • In general three position sensors are needed to drive three phases SRM. Single position sensor driving method for three phases Switched Reluctance Motor(SRM) is proposed in this paper. By using single position sensor the cost of SRM is reduced. But position sensor the cost of SRM is reduced. But position detection at the staring is needed for single position sensor driving method. In this paper we propose the active align method to detect the relative position of rotor to three phases and align to the nearest phase. We proved the validity of the method by experiment and compare with other method.
