Abstract Based on a 12/8 full-period bearingless switched reluctance generator (FPBSRG), the expression of the generating current is derived under different excitation regions according to the equations of the two windings. Accordingly, the mathematical model of the output power is built in the excitation region. Then, the influences of the excitation region on the output power in the excitation period and freewheeling period are analyzed. Finally, the method of selecting the optimized excitation region is proposed. In the guide of the theory, a series of experiments are carried out. The results show that the proposed method is effective when the generator’s shaft is levitated.
