Design of Novel Hybrid Excitation Segmented-Rotor Switched Reluctance Motor for Electric Vehicle

In this paper, twelve permanent magnets are added to stator port section of the 12/10 segmented-rotor switched reluctance motor to form a hybrid-excitation segmented-rotor switched reluctance motor, which has the advantages of large average torque, low torque ripple, and good fault tolerance etc. In order to further exert the performance of the motor, a multi-objective optimization design using Taguchi method is proposed. First, the basic structure and working principle of the motor are described. Then some basic design principles of the motor are given, the basic design parameters of the motor are given on this basis. Then parameter sensitivity analysis was carried out, parameter screening was carried out, and then Taguchi orthogonal table was established according to the factor level, and the best combination was obtained with the multi-objective optimization function, and its performance was compared. Finally, the steady-state and dynamic performance analysis after optimization is analyzed, which verifies the reliability of the multi-objective optimization scheme.
