N2 - Axial flux permanent magnet (AFPM) machines are welcomed widely in propulsion systems due to their compactness and high torque density. Thus, multi-phase topologies are also studied for AFPM machines. This paper proposes a novel dual three-phase dual stator AFPM machine with mechanical offset. The mechanical offset angle can achieve any phase difference between two sets of three-phase windings. The influence of offset angle in the cogging torque of the machine is analyzed. It can affect the amplitude of the cogging torque. In addition, finite element analysis is conducted to optimize the offset angle and pole arc ratio. Finally, the offset angle and pole arc ratio are determined to be 1.5° and 0.8, respectively. The cogging torque of the machine is 0.31 Nm, while the average torque is 11.91 Nm. In addition, the modulation ratio of space vector modulation for the proposed machine nearly remains the same when compared with conventional dual three-phase machines.
