Reluctance Mesh-Based Modeling of Switched Reluctance Machines

Abstract

Design of switched reluctance machines requires repetitive finite element (FE) simulations with considerable computational time and burden. These simulations slow down the design process and require powerful computational resources. The magnetic equivalent circuit (MEC) technique resembles an alternative with a reasonable computational time and fair accuracy. This paper proposes a reluctance mesh-based magnetic circuit model of SRMs. Here, MEC models of a 3-phase 6/4 and a 4-phase 8/6 SRMs are developed. The models provide the airgap flux density in addition to the static flux-linkage and torque characteristics. The results obtained by the MEC models show a good agreement with those obtained using the corresponding FE models.
