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
