The stator split-type hybrid excitation motor is a new motor which has the ability ofself-regulating magnetic field, and combined the advantages of hybrid excitation motor, flux-switchingmotor and disc motor. The new motor is studied in this paper, inductance parameters of the motor areanalyzed by using finite element analysis method. The simulation model of fuzzy adaptive PI excitationcontrol system is established. The changes of closed-loop when load constantly and speed changed areanalyzed. The results showed that the fuzzy adaptive PI algorithm can effectively reduce the voltageovershoot and obtain the better robustness of the system. The simulation platform of the system is built,the results coincided with the simulation results, verified the correctness of the theoretical analysis andsimulation results.
