Abstract：In order to improve the operating performance of the hybrid stepping motor(HSM),and completely solve the defects resulting from its structural configuration of rotor-mounted permanent magnet,a novel stator-permanent-magnet stepping motor(SPMSM) with permanent magnets located in the stator is originated.It can be proved that the SPMSM owns exactly the same operating principle as the HSM,whereas a much more simplified construction,a higher torque and power density as well as a higher efficiency can be achieved.Theoretical analysis regarding to the operation principle and key technology employed for the SPMSM are performed,while a comparison between the SPMSM and the DSPM machine is also conducted.Simultaneously,based on the normalized design idea of stepping motors,a normalized analysis calculation method applicable to the SPMSM is also put forward,which takes full advantage of the 2-D field-distributed characteristic of the SPMSM ignoring the end effects.By using the method,the motor’s flux linkage,electromotive force(EMF),torque,and power can be calculated.In addition,a prototype of 2-phase 8-pole 50-tooth SPMSM has been manufactured,with the practical operating feasibility validated by experiments.Both finite element simulations and experimental results show that the adopted theoretical analysis approach and the established power equation can not only act well to reflect the machine’s characteristics but also apply well to certain variations of the machine’s structural topologies and dimensions,and which might lay a foundation for further research on the design and analysis of the proposed SPMSMs.
