A mathematical model of switched-reluctance motor drive for electrical spindle in synthetic yarn machine

Abstract

Abstract The article deals with the modeling of switched-reluctance drive motor for electrical spindle in synthetic yarn machine. We propose to use the backward differentiation formula to solve a system of algebraic-differential equations that governs electromagnetic processes in switched-reluctance electrical machine. The considered approach allows us to avoid the use of numerical differentiation of current and turning angle dependence of the phase flux linkage. As a result, the mathematical model does not significantly depends on basic data and has good convergence. This article shows the switched-reluctance electrical machine modeling. The use of method proves the correctness of the chosen approach
