Switched reluctance machine (SRM) has attracted more attention recently for its simple structure and high reliability. In this paper, an analytical method for solving the magnetic field in SRM is illustrated utilizing the Schwarz-Christoffel conformal mapping method. With the help of Matlab SC tools, a general radial flux SRM with linear material characteristic is analyzed. The flux density distribution along a contour in the airgap is obtained and torque is calculated using Maxwell stress tensor and compared with finite element method results. The comparisons show a good agreement and reveal the advantage of conformal mapping in time saving.

Performance improvement and comparison of concentrated winding segmental rotor and double stator switched reluctance machines Bostancı, Emine; Cosoroaba, Eva; Moallem, Mehdi; Fahimi, Babak (2017-01-12) Switched reluctance machine (SRM) is well known for its simple and robust design as well as its good high speed performance. On the other hand, its shortcomings are the moderate power/torque density, high torque ripple and high acoustic noise. Having one of the simplest mechanical designs, these machines have potential for a significant improvement. Accordingly, segmental rotor and double stator SRM (DSSRM), which also has a segmental rotor shared by two stators, are designed to improve the performance of S...
Optimum design of multistep spur gearbox Öztürk, Fatih Mehmet; Department of Mechanical Engineering (2005) Optimum design of multistep gearbox, since many high-performance power transmission applications (e.g., automotive, space industry) require compact volume, has become an important interest area. This design application includes more complicated problems that are not taken into account while designing single stage gear drives. Design applications are generally made by trial and error methods depending on the experience and the intuition of the designer. In this study, using Visual Basic 6.0, an interactive p...
Modeling of Multi Open Phase Fault Condition of Multi-phase Permanent Magnet Synchronous Motors Fei, Marco; Zanasi, Roberto (2011-09-10) This paper deals with the modeling of multi-phase permanent magnet synchronous motors under multi open phase fault condition. The presented model is suitable for generic number of phases, generic shape of the rotor flux and generic number of open circuit faults. The motor model in fault condition can be used for faults occurring on both adjacent and not adjacent phases. The model can be very useful both for simulation and implementation of fault-tolerant control strategies.
Direct Torque Control of a 4-Phase Switched Reluctance Machine Petrus, V.; Pop, A. -C.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10) Due to its doubly salient structure and highly nonlinear behavior, the Switched Reluctance Machine (SRM) operates with very high torque ripple. To overcome these inconveniences different average and instantaneous torque control techniques were developed. This paper presents an instantaneous torque control technique named Direct Torque Control (DTC) implemented on a 4-phase, 8/6, 0.75kW SRM. Simulations results with modified flux observer and with fast torque response are presented and discussed, along with ...
Effects of control parameters on SRM performance: A parametric search Bizkevelci, E.; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2007-09-12) This paper investigates the effects of the SRM control parameters on torque ripple and efficiency. The average shaft torque, torque ripple and the torque per ampere variation of the motor are observed at different turn-on and conduction angles. The study is performed using simulation software developed by the authors. Some experimental results are presented which indicate that the software promises to be accurate. The findings of the study are presented to give an idea about the optimum switching strategy t...
