摘要：
In the paper, a novel dual-rotor permanent magnet synchronous generator (DRPMSG) for wave power generation is designed. The no-load reaction characteristics and load reaction characteristics of the DRPMSG are analyzed with back-EMF, air gap magnetic density harmonic, torque and current results presented. A significant advantage of this machine is that it can achieve variable stiffness adjustment for wave energy conversion. The output power of DRPMSG is a summation of the inner and outer rotor's power. Therefore, it can transform wave power into electric power more steadily since it can operate in a wider wave speed. The simulation results verify the feasibility of the optimized DRPMSG and the effectiveness of the proposed design scheme. (C) 2020 The Authors. Published by Elsevier Ltd.
