Full-Speed Domain Performance Comparison of Traditional and Segmented-Rotor Switched Reluctance Motors

In this paper, to investigate the superiority of the segmented rotor structure, a full-speed domain comparative study of the traditional and segmented-rotor switched reluctance motors is put forward, which comprehensively reflects the performance differences between the two motors. The static inductance characteristics of these two motors are analyzed by means of electromagnetic simulation, followed by a comparative performance analysis under three operating conditions: constant torque region, constant power region, and series excitation region, and the reasons for the performance differences are given. Finally, the external characteristics of the two motors are analyzed comprehensively. The work in this paper provides guidance for the optimal design of SSRM.
