N2 - This paper proposes a novel flux reversal permanent magnet machine with DC excitation source, which aims to reduce the permanent magnet material usage as well as to improve the torque capability of machine. Compared with the conventional flux reversal machine, the additional DC coils is applied in armature windings to provide additional DC excitation source. Therefore, PM excitation source is saved and the magnetic reluctance is reduced. Moreover, the proposed machine structure reduces the air-gap thickness. It means that this proposed machine is able to achieve higher torque compared with the conventional flux reversal machine. In addition, to achieve the optimized torque performance, the proposed machine is further optimized. In this paper, the structure of proposed machine is introduced with its working principle. The whole optimization process is presented through different steps. Finally, the electromagnetic torque performance of the proposed optimized machine is analyzed and verified with finite element method.
