Due to advantages of simple structure, large starting torque and high reliability of Switched Reluctance Motor (SRM), it has been used in many fields. However, SRM shows lower torque density compared with permanent magnet motor. In this paper, a novel segmentation stator SRM is proposed, which had 12 PMs located on both side of 6 stator block to form Segmented Stator Hybrid Excitation Switched Reluctance Motor (SSHESRM). Firstly, the topology structure and working principle of SSHESRM was introduced, and proven the intensified effect of PMs to air-gap flux density based on Magnetic Equivalent Circuit (MEC). Then, the Finite Element Method (FEM) was used to analysis impact of PMs on torque density and obtained the optimal thickness of PMs. Finally, it is proved that the average torque of SSHESRM is increased by 34.2% and torque ripple is decreased by 19.3%.
