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 SRM. Both of these machines have full pitch or concentrated windings topologies. Among these, concentrated winding topology is highly preferable due to reduced amount of copper and modular winding design. However, this requires a careful magnetic design optimization. This study introduces new magnetic design aspects for segmental rotor SRMs. Consequently, the advantages of DSSRM structure in terms of energy conversion efficiency and torque/power density are addressed in detail.

Analytical calculation of the electromagnetic field in SRM using conformal mapping method Gu, Lei; Bostancı, Emine; Moallem, M.; Wang, Shiliang; Devendra, Patil (2016-07-22) 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 compar...
Opportunities and Challenges of Switched Reluctance Motor Drives for Electric Propulsion: A Comparative Study Bostancı, Emine; Parsapour, Amir; Fahimi, Babak (2017-03-01) Selection of the proper electric traction drive is an important step in design and performance optimization of electrified powertrains. Due to the use of high energy magnets, permanent magnet synchronous machines (PMSM) have been the primary choice in the electric traction motor market. However, manufacturers are very interested to find a permanent magnet-free alternative as a fallback option due to unstable cost of rare-earth metals and fault tolerance issues related to the constant permanent magnet excita...
Performance Calculation of SR Motors for Optimum Design and a Washing Machine Application Ertan, Hulusi Bülent (2008-09-09) This paper aims to develop an approach for performance calculation of an SR motor, which is suitable for use within mathematical design optimization. For this reason the requirement is to develop procedures, which are both accurate and fast. The procedures adopted here rely on flux-linkage-current-position curves of the motor. A series of tests are carried out on a test motor. The results are compared with estimations from the developed algorithms. It is shown that the current waveform, torque-speed curve, ...
Design of synchronous reluctance machines with a wide speed range Yılmaz, Yusuf Basri; Bostancı, Emine; Department of Electrical and Electronics Engineering (2021-9-10) Synchronous reluctance machines (SynRMs) are a good alternative for traction and industrial applications due to their good power density, low cost and high efficiency. However, they suffer from high torque ripple, low power factor and poor high speed performance due to their singly excited nature. To overcome these challenges, rotor geometries are optimized to get a low torque ripple and ferrite magnets are inserted in the flux barriers to get a higher power factor and a better high speed performance. Thi...
A ZVS-Resonant Bifilar Drive Circuit for SRM with a reduction in Stress Voltage of Switches Ebrahimi, Seyyedmilad; Najmi, Vahid; Ebrahimi, Seyedyaser; Oraee, Hashem (2011-09-10) Switched Reluctance Motors (SRMs) are widely used in high-speed and low voltage applications because of their attractive features such as robustness and simplicity. No winding on the rotor of this type of motors allows reaching high speed which is desired for many applications. Drive circuits of SRNIs also play an important role in their performance and operation. In this paper, a new bifilar drive circuit for this type of motors has been proposed. This novel configuration has been tested and investigated b...
