6/4 SRM electromagnetic modeling and control by using Finite element method

Autor: Guettaf Abderrazak, Ali Arif, Kassimi Youghourta

Publikováno v: 2021 International Conference on Electrical, Communication, and Computer Engineering (ICECCE).

This paper provides a new path to the precise simulation online of an SRM 6/4 drive and the implementation of the currently switched reluctance motor control system (SRMs). For 6/4 SRM, the mathematical equation of inductance of this motor model is g

Publikováno v: Volume: 5, Issue: 1 177-182
International Journal Of Renewable Energy Research

We investigated the optical properties of pure and Aluminum doped zinc oxide thin films as the n-type semiconductor. In this paper we have focused our attention on the creation of a new approach to calculate the optical gap and Urbach energies, these
