An electric drive is an indispensable part of any mechanism. Without it, the the functioning of any industry is impossible, especially in the railway. It allows you to automate technological processes and increase their efficiency. For efficient railway transport, it is necessary to increase the level of technical development of traction rolling stock, which is possible through the use of promising types of electric machines, one of which is a switched reluctance motor. To create a highly efficient and technological switched reluctance electric drive, it is necessary to have information about the relationship between the geometric dimensions of its magnetic system and the average value of the electromagnetic moment. The purpose of this article is to determine the strength and direction of the relationship between the average value of the electromagnetic moment and the changing geometric values of the tooth-groove zone of the object under study. The numerical value of the electromagnetic moment was obtained using the stochastic method in the MATLAB application package, which directly interacted with the FEMM version 4.2 program, which is based on the finite element method. The research carried out in the article and the results obtained allow us to conclude that there is or is not an appropriate connection between the considered elements of the magnetic system design and the value of the electromagnetic moment.
