A New Technique for Radial and Tangential Force Calculation Time Reduction for the Optimization Process of SRMs

open access: yesIEEE Access, 2023
This article introduces a new technique for reducing the time of calculating radial and tangential force density waves of switched reluctance machines (SRMs). The method is based on the finite element (FE) simulation of a fraction of an electrical cycle.

Design and analysis of switched reluctance motor with FEM based Ansys-Maxwell

open access: yesMANAS: Journal of Engineering, 2022
In this study, radial forces that create noise, which is a fundamental problem in Switched Reluctance Motor (SRM), are investigated. Since radial force causes stator vibrations and noise caused by magnetic field, a new switched reluctance motor model ...

A Torque Sharing Optimization Control Strategy for Switched Reluctance Motors [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban
Aiming at the problem of larger torque ripple of switched reluctance motors, a compensation cosine torque sharing optimization control strategy for switched reluctance motors was proposed by improving the traditional cosine torque sharing function. Based

Optimal current waveforms for switched-reluctance motors [PDF]

open access: yes2016 IEEE Conference on Control Applications (CCA), 2016
In this paper, we address the problem of finding current waveforms for a switched reluctance motor that minimize a user-defined combination of torque ripple and RMS current. The motor model we use is fairly general, and includes magnetic saturation, voltage and current limits, and highly coupled magnetics (and therefore, unconventional geometries and ...
