摘要：
In this article, a new dual-modulator magnetic-geared machine (DM-MGM) is proposed for tidal-power generation with the virtue of high-torque output at low speed. First, the requirement of the DM-MGM for tidal-power generation is derived. Then, the flux-modulation principle and flux-enhancing effect of the extra modulator of the proposed DM-MGM are elaborated. After that, a finite-element analysis and multi-objective genetic algorithm (FEA-GA) combined method is used to solve a multi-objective optimization problem for the DM-MGM design. The electromagnetic performances of the optimized DM-MGM with different pole-pair combinations are quantitatively compared by FEA. The results show the effectiveness of the proposed machine, which is suitable to be applied in the tidal-power-generation scenario.
