Comparison of torque characteristics for a novel segmented and a conventional switched reluctance motors

Abstract

The extensive applications of switched reluctance motor (SRM) have been limited due to its drawback of torque ripple. Thus, the reduction of torque ripple is an important problem in studying the SRM. A novel 16/10 segmented SRM (SSRM) is proposed in this paper. The proposed SSRM performs well in terms of torque ripple and tolerant-fault characteristic. The stator of the proposed structure is constructed from exciting and auxiliary stator poles, while the rotor consists of a series of discrete segments. Moreover, the torque ripple is evaluated by comparing with the conventional 8/6 SRM. Finally, the tolerant-fault characteristic of the proposed SSRM and conventional SRM are compared as well. The finite element method (FEM) is employed to demonstrate the prominent advantages of static and dynamic characteristics of the proposed SSRM.

A Review on Predictive Control Technology for Switched Reluctance Motor System

“…To fully tap into the benefits of SRMs, various methods have been suggested to enhance their performance [31][32][33][34]. Angle position control and current chopping control are the traditional control methods for SRM [35][36][37][38][39][40]. With the development of current control technology, people are further studying different aspects of SRM control, such as sliding mode control [41][42][43][44][45][46], sensor-less control [47][48][49][50][51], fault-tolerant control [52][53][54][55][56][57], robust control [58][59][60], and minimizing torque ripple control [61][62][63][64].…”
