Multi-mode Excitation Analysis and Design of a New Hybrid Excited Modular Stator Permanent Magnet Switched Reluctance Machine

In this paper, a new hybrid excited modular stator permanent magnet switched reluctance (HE-MSPMSR) machine is proposed. The design and multi-mode excitation characteristics of the HE-MSPMSR machine are studied. Firstly, the structure, basic working principle and design ideas of the motor are summarized, and the stator of HE-MSPMSR machine not only includes the stator core and three-phase armature winding, but also includes the excitation coil and permanent magnet as the excitation source. The motor can change the air gap magnetic field flux size by controlling the on-off of the excitation magnetic source. On this basis, the HE-MSPMSR machine can achieve the torque multiplication effect under the condition of magnetization. Compared with the traditional switched reluctance motor, the motor has the advantages of low speed and large torque, high power density, high torque density and high efficiency, and its driving performance is better than that of traditional switched reluctance motor. After clarifying the design constraints and specifications, the preliminary design results based on finite element analysis are demonstrated. Finally, a prototype will be constructed, and the experimental study will be conducted to verify the validity of the design and analysis results.
