Abstract: Contra-rotating permanent magnet brushless DC motor uses permanent magnet as the outer rotor，the armature winding as the inner rotor，both inner and outer rotor interacts on the reverse rotation by means of the magnetic force. Based on the analysis of the mathematical model of contra-rotating BLCDM, the model of BLDCM was established by the modular design in Matlab/Simulink, and the simulation experiment was accomplished with a propeller loads. The simulation results are consistent with the theory analysis, and the method is valid. The parameter of this method is suitable for verifying the reasonability of other control algorithms and provides a new way for further research of the contra-rotating BLDCM.
