A novel brushless dual-mechanical-port dual-electrical-port machine

In this digest, a novel BLDD machine topology is proposed. Auxiliary tooth structure is adopted, hence modulation winding and regular winding can be both wound as non-overlapping windings. Meanwhile, spoke PM array is set between steel segments in the modulation rotor, hence the torque component produced by regular PM machine increases substantially. More details about machine performance and function will be given in the full paper.
