Summary In comparison to one‐layer switched reluctance motor (SRM), a multi‐layer SRM is able to produce much larger output power and it can be considered as a good candidate for high‐power electric machine. For a multi‐layer SRM, different layers have the same performances and they are completely independent from electromagnetic point of view. Therefore, analysis of one layer can be only carried out to determine the electromagnetic characteristics of the multi‐layer SRM. In the present paper, a fast and simple magnetic equivalent circuit (MEC) model is introduced for one‐layer SRM and it is then used for performance prediction of the multi‐layer SRM. Due to high torque ripple of the SRM, a simple solution is suggested for different types of the multi‐layer SRM by which torque ripple of this motor can be reduced significantly. To evaluate the done modeling and the suggested torque ripple method, simulation results are presented for a typical multi‐layer 8/6 SRM.
