The operating principle of brushless electrically excited synchronous machine (BEESM) and field modulation principle of hybrid were studied. The inductance parameter model of BEESM with hybrid rotor was established by combining the superposition method and the winding function method. The analytical calculation method of inductance parameters of BEESM with hybrid rotor was studied. The variation of inductance parameters with the rotor position was obtained by programming calculation, and the inductance parameters of BEESM were calculated by the finite element method. A prototype machine was manufactured, inductance parameters of machine was measured by method of static test. The analytical results are compared with the finite element results and the experimental results respectively, and the correctness of calculation method of inductance parameter is verified. It lays theoretical basis for further simulation and analysis of this kind of machine.
