Abstract: The stator-permanent-magnet hybrid stepping motor（SHSM） is a new kind of hybrid stepping motors, which has the same operation principle as the rotor-permanent-magnet one（RHSM）, whereas superiorities are such as the simpler rotor structure, higher mechanical robustness, higher torque and power density, easy PM dissipation, and simple design and analysis. To reasonably evaluate the performance of these two kinds of HSM, comparative analysis was carried out in terms of the PM air-gap flux density, the optimal core length, the PM torque, the detent torque and the torque ripple, the PM flux linkage and the no-load back-EMF, the PM leakage flux and the utilization rate and the stator yoke flux density. A prototype of the 2-phase 8-pole 50-tooth SHSM was fabricated and tested to verify the motor’s operation feasibility. Based on prototype’s parameters, simulation models of the two kinds of HSM were built and analyzed by finite element method（FEM）. Accuracy of the theoretical analysis was verified by FEM and experimental results, which provides a theoretical basis for further extension and applications of the novel SHSM.
