In the hybrid excited flux-switching motor (HEFS), the magnetic field can be modulated by both the dc field current and the d-axis current. According to HEFS magnetic modulation characteristics and vector control principle. A maximum rate of torque value to copper loss (MRTC) controlling means based on voltage feedback zone speed regulation is proposed in this article. First, the control strategy determines the running area by the error of the motor feedback voltage comparator. In different speed areas, by establishing different objective functions of the copper loss of the HEFS, the distribution of dc excitation current and armature current was optimized under a certain load torque. With the control method proposed in this paper, achieves the goal of wide speed range and MRTC for HEFS. The proposed scheme is verified by results of simulation.
