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 excitation. In this paper, a new comprehensive review of electric machines (EMs) that includes various new switched reluctance machine topologies in addition to conventional EMs such as PMSM, induction machine, synchronous reluctance machine (SynRel), and PM-assisted SynRel is presented. This paper is based on performances such as power density, efficiency, torque ripple, vibration and noise, and fault tolerance. These systematic examinations prove that recently proposed magnetic configurations such as double-stator switched reluctance machine can be a reasonable substitute for permanent magnet machines in electric traction applications.

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...
Prediction of torque and inductance displacement characteristics of asymmetrically slotted variable-reluctance motors using a simplified model for numerical field solution
Ertan, Hulusi Bülent (1999-09-01)
For prediction of static and dynamic performance of doubly-salient motors, it is essential to know their flux linkage-position-excitation characteristics and also the static torque characteristics. At the design stage determination of these characteristics presents difficulties because of highly nonlinear behavior of the magnetic circuit. It is possible to use numerical field solution of the complete motor to obtain this information. This, however, requires expertise on a professional program and may be exp...

The purpose of this study is to seek the optimal stator and rotor saliency number of a switched reluctance motor (SRM) for hybrid electrical vehicle (HEV) applications. For this purpose, first a previously developed SRM analysis software is investigated to identify possible errors in implementation of both the theory and the coding. Performance prediction method is based on the use of normalized force and permeance data produced via numerical field solution, and a polynomial based interpolation is introduce...

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...
