“…For the research of the vehicledriven permanent magnet motor, the magnetic field of the hybrid excitation motor can be adjusted online by adding additional electric excitation winding [6], or by adding a negative d-axis flux-weakening current to weaken the magnetic field of the permanent magnet motor [7]. In [8] and [9], the internal magnetic field of the motor is adjusted by an external mechanical device. All these methods change the total flux of the excitation source to realize the regulation control of the effective main flux.…”

In this paper, a controllable leakage flux reverse salient permanent magnet synchronous motor(CLF-RSPMSM) is designed, which has the advantages of wide speed range and low irreversible demagnetization risk. Firstly, the principle of controllable leakage flux and reverse saliency effect is introduced, and the design of the rotor flux barrier is emphatically discussed. Secondly, multiple design variables are stratified by the comprehensive sensitivity method, and the main variables are screened out. Then the relationship between the main variables and the optimization goal is discussed according to the response surface diagram. Thirdly, a sequential nonlinear programming algorithm(SNP) is used to optimize the three optimization objectives comprehensively. Finally, the electromagnetic performance of the proposed motor is compared with the initial IPM motor, the mechanical strength of the proposed rotor is analyzed, and the results verify the effectiveness of the design and optimization method of the proposed motor.
