As a starter, the switched reluctance machine (SRM) features a significant output torque. As a generator, the doubly salient electromagnetic machine (DSEM) has excellent voltage regulation characteristics. To combine the benefits of both types of machines and reduce the length of flux paths, a segmental rotor dual mode reluctance starter generator (SR-DMRSG) for vehicles is proposed in this article. This machine transitions between two operating modes by adjusting the linkage between the armature winding and the variable winding. First, the research object is identified as the SR-DMRSG with a 12/8-pole structure by establishing the corresponding relationship between the number of stator poles and the number of segmented rotors. The magnetic chain, electric potential, and other electromagnetic characteristics of the SR-DMRSG are analyzed by using the finite element method. The study findings demonstrate that the SR-DMRSG displays a 5.46% increase in peak torque when compared with a conventional SRM. Moreover, it operates as a generator which is effortless to regulate. The total harmonic distortion (THD) of the back electromotive force (EMF) of the armature winding decreases by 8.1%. The machine’s feasibility has been verified by simulation and experimental results. It has been confirmed that the SR-DMRSG has high starting torque and effective voltage regulation.
