In this article, a novel hybrid excited modular stator permanent magnet switched reluctance (HE-MSPMSR) machine is proposed. The three-phase armature winding, dc excitation winding, and permanent magnets (PMs) are set on the modular stator cores, where the air gap flux can be changed by controlling the dc excitation winding current. Compared with the traditional switched reluctance (SR) machine, the motor has the advantages of high power density, high torque density, and high efficiency, and its driving performance is better than that of the traditional SR machine. The design and multimode excitation characteristics of the HE-MSPMSR machine are investigated, and the machine structure and operating principle are summarized in detail. After clarifying the design constraints and specifications, the preliminary design results based on the finite element analysis are demonstrated. In addition, the influences of the main parameters on the torque and torque ripple are analyzed, and the optimal design parameters are given. Finally, a prototype is constructed, and the experimental study will be conducted to verify the validity of the design and analysis results.
