Abstract-Electrical drives are one of the major consumers of electrical energy and their penetration in the market is still growing. Hence, for many drive applications efficient, reliable and cost effective solutions have to be found. Switched reluctance drives (SRD) offer a potential solution when focus is mainly on cost and robustness. However, to benefit from the unique advantages of this machine type a deep understanding of its strongly non-linear behavior is required. After discussing some major differences to classic rotating field machines, this paper presents a broad overview of the state of the art of SRD taking into consideration all aspects relevant to machine modeling, design and control development process. Finally, applications on the market utilizing SRDs and the focus of current research is presented. After reading this paper the reader will be able to assess if this modern drive technology could be advantagous in a given application.

“…Meanwhile, the recently proposed short flux path SRMs with an E-core and a C-core are possible low-cost solutions for variable-speed applications [2]- [4]. With their short flux path, the distance of each exaction path is reduced.…”

“…Meanwhile, the stator has lower core losses due to the absence of flux reversals in the stator core and a phase flux path that only traverses two-thirds of the back iron, which lowers the magneto motive force (MMF) requirements. The goal of the segmental rotor type SRMs [4], is to reduce the iron loss. The rotor cores are cut into segmental parts and embedded into the rotor body.…”

A novel 12/10 axial field switched reluctance motor (AF-SRM) is proposed for cooling fan applications in this paper. Unlike from conventional structures, the proposed motor uses the axial field instead of the radio field, the rotor is constructed from a series of discrete segments, and the stator poles are constructed from two types of stator poles: exciting and auxiliary poles. This concept improves the torque capability of a previous design by reducing the copper volume, which leads to a higher efficiency. To verify the proposed structure, the finite element method (FEM) and Matlab-Simulink are employed to get characteristics of the proposed SRM. Finally, a prototype of the proposed motor was tested for characteristic comparisons.

“…In addition to employing the control schemes, modifying the geometry of the SRMs can overcome the above mentioned disadvantages partly as well. In [11], Mecrow et al propose a novel SRM with full pitch windings to improve the torque density at the expense of the longer end-windings, which is not suitable for short axial length machines. In [12], Z.Y.…”

This paper proposes a novel 16/10 segmented rotor switched reluctance motor (SSRM) for belt-driven starter generators (BSGs). Different from conventional SRMs, the stator of the proposed SSRM consists of two types of stator poles, i.e., exciting and auxiliary poles, and the rotor is constructed from a series of discrete segments. The topology and operation principle of this proposed SSRM are illustrated firstly, and then the design rules are listed. In addition, the finite element method (FEM) is employed to get the static and dynamic characteristics of the proposed SSRM. Finally, the simulation results are presented to show the validity of the proposed SSRM for BSGs.
