This paper presents a comparative evaluation of power electronic control approaches for vibro-acoustic noise reduction in High Rotor-Pole Switched Reluctance Machines (HR-SRM). It carries out fundamental analysis that can be used to target acoustic and vibration reduction. Based on the comprehensive study, four candidates have been identified applied HR-SRM drive evaluate their effectiveness id...

The switched reluctance motor (SRM), an environmentally friendly machine, is suitable for application in electric vehicles (EV) recent days. This paper presents SRM sensitivity analysis focussing on weight of the materials used stator and rotor use vehicle application. Two structures are considered, namely normal tooth tapered tooth. Thirteen widely considered these two to perform proposed anal...

This paper presents the design of a switched reluctance motor (SRM) for direct-drive propulsion application light sport aircraft. The SRM is designed to replace 70 kW permanent magnet synchronous used in aerospace with similar dimensional constraints. As means achieving high torque density and efficiency, multi-objective framework optimize geometry parameters motor. In order further reduce weig...

The paper presents a general algorithm for the specification of a screw machine geometry. The conjugancy condition was solved numerically which thereby enables a variety of primary arc curves to be introduced. In addition, an optional numerical derivation of primary arcs enables any analytical function and even discrete point functions to be used for the primary arc. The approach also simplifie...

Most past investigations of dual-spin spacecraft have assumed that the platform and rotor are symmetric and rigidly connected. Recently, Cretcher and Mingori, Wenglarz, Willems, and Bainum have considered the effects of flexibility in different parts of dual-spin spacecraft. Scher and FarrenkopP have considered the effects of an asymmetric rotor rigidly connected to the platform. However, the e...

nowadays the use of the switched reluctance motors (srms) has been considerably increased in various home and industrial applications. despite of many advantages of this type of motors, such as simple structure, low cost, and high reliability, the main disadvantage of them is the generation of high torque pulsation. this paper presents a novel method to optimize a typical srm such that the torq...

We evaluate an external segment-type switched reluctance motor (ESSRM) generator via simulations and experiments on actual ESSRM. In the simulation, shape of ESSRM was optimized using a genetic algorithm with two sizes varied as parameters. As result calculating 480 different shapes, it is found that model by has 1.45% higher power generation efficiency 95.08% 634W generated 2,896W than single ...

This paper presents a new design to reduce torque ripple in Switched Reluctance Motors (SRMs). Although SRM possesses many advantages in terms of motor structure, it suffers from large torque ripple that causes problems such as vibration and acoustic noise. The paper describes new rotor and stator pole shapes with a non-uniform air gap profile to reduce torque ripple while retaining its average...
