Switched reluctance machines (SRM) are an alternative to conventional and permanent magnet (PM)-based machines. They are simple, robust and fault tolerant, and able to reach very high speeds with high efficiency. However, they operate with high torque pulsation and are noisy. Also, a nonconventional power converter type and specific control schemes must be included. Furthermore, SRM operation is characterized by high nonlinear features, which makes it difficult to be modeled and controlled. SRM energy conversion principles are a keystone to understand its operation. SRM efficiency increases with speed, where core and mechanical losses are more significant. For this machine, core loss estimation is a complex task, due to the nonlinear behavior of the magnetic materials. In addition, flux waveforms are not sinusoidal and particular waveforms appear in different core sections. Empirical formulas are usually considered in core loss estimation, but this is insufficient for SRM.

“…For any electrical machine, loss estimation is fundamental for design optimization and control. Furthermore, an accurate loss evaluation is vital for achieving the desired operation conditions [7]. Like in other electric machines, SRM losses occur in stator windings, core materials (stator and rotor), and mechanical moving parts.…”

This research introduces a novel magnetically isolated phase structure for switched reluctance motor, namely, as Septi-Segment SRM (SSSRM), which is proper for high torque/volume and with lowest leakage flux in different fields of industries. The SSSRM contains seven stator layers that are isolated from each other magnetically, also each of them include an assembly of 4/4 stator/rotor poles. The three layers are energized at the same time for generating higher torque with lower ripple compared with the typical SRM. Furthermore, this configuration results other advantages, such as easy cooling and independent phases. To evaluate the proposed motor performance, the configuration is introduced at first. Secondly, the motor profiles as flux linkage, flux density, self/mutual inductance and motor torque are assessed using a 3D finite element method (3D-FEM). An SSSRM has been manufactured with a test bench in the laboratory, and the experimental results of the new motor and typical type were compared in the same volume and area. The results and comparative study clearly demonstrate the prominent features of the proposed motor for various applications.

“…The reluctance motor has begun to realize its potential in the new era of power electronics and computer-aided electromagnetic design [5]. Furthermore, it is considered to be ideal for various safety-critical claims in medical, aerospace and automotive applications, which it is desirable for applicants to be fault tolerant [6]. Despite reliability and robustness of the SRMs, the electrical and mechanical faults can appear during malfunction [7,8].…”

The performance of the Switched Reluctance Motors (SRMs) in different applications has widely been investigated by various studies. The research areas are oriented toward fault effects on electromagnetics behavior and its diagnosis for operation improvement. One of the most observed faults is the stator winding short circuit which may lead to produce the unbalanced distribution of magnetic field. In this paper, it is attempted to firstly introduce the conventional SRM and new structure of double stator SRM (DSSRM). Secondly, by means of three dimensional finite element method (3D FEM) the effects of short-circuit faults (SCF) on motor profiles are investigated, in which static and dynamic behaviors of the motor in healthy and several SCF conditions are evaluated. A new method namely as maximum current point tracking (MCPT) is introduced to evaluate the SCF in SRM, so an index is proposed to detect the numbers of shorted turns in faulty phase. The overall outcomes highlight the advantages of using this method and index which is general enough to be applied to any type of SRM.
