Similarity and Comparison of the Electrodynamics Characteristics of Switched Reluctance Motors SRM with Those of Series DC Motors

Abstract

The switched reluctance motor is appreciated in variable speed drives through his simplicity of design, his low cost, his high reliability and high ability to regulate which allow him to compete with the other common types of electric drives. The mathematical modelling of switched reluctance motors (SRM) allows his study in the areas of research and conception. In this paper, we present the developing of a methodology using the combined model of switched reluctance motor drive bases in standard equations of electrical machines with the field theory analysis of magnetic circuit. Then, the elaboration of mathematical models for switching reluctance motor (SRM) proposes his application based on a similarity with series DC motor to simplify the conception of control of electrical drives systems [1] with Closed Loop Control.

“…From (10) we put (13) where j = 1, 2, 3, 4 Equation ( 10) can be rewritten as (14) Differentiating equation ( 14) with respect to time, we get (15) From equation (11), we set: 8/6 switched reluctance motor with 4 phases the state vector is defined as follows x = [θ, ω, i 1 , i 2 , i 3 , i 4 ] T = [x 1 , x 2 , x 3 , x 4 , x 5 , x 6 ] T . The equation of the motor's state as follows.…”

“…Addressing this issue poses a key challenge that needs to be resolved [9]. Several studies have proposed mathematical models for SRMs and control strategies for switched reluctance motor drive systems based on these models [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. While [10,17,24] address the basic learning model of the SRM, [11] presents the nonlinear model of the switched reluctance motor with consideration of the influence of mutual inductance between phases.…”

The issue of flux is also mentioned in [12,13], where the authors use third-order Fourier series analysis to approximate the flux curve and compare it with of hybrid electric vehicle systems using SRM.…”
