A Pole-Modulation Brushless Dual Mechanical Port Machine (PMB-DMPM) model is presented. This model removes brush, the stator and its embedded winding are ordinary, the outer rotor is single-layer concentric cage, and the inner rotor is permanent magnets. By the modulating function of the cage rotor, the stator windings and the permanent magnets of the inner rotor produce a magnetic field individually, whose rotational speed and magnetic pole’s number are consistent with each other, and the energy can delivery through the stator, the outer rotor and inner rotor. The simulation results show that the machine model can achieve a good magnetic field modulation effect, and validate the proposed model’s feasibility.
