A Novel Efficient and High-Capacity Permanent Magnet Vernier Machine for Urban Intelligent Wind Power Systems

The development of wind power systems necessitates higher flexibility and power density requirements for wind turbines. This paper proposes a novel permanent magnet vernier machine (PMVM) designed for urban intelligent wind power systems. The PMVM features dual windings and dual permanent magnets (PMs). On one hand, it leverages the dual modulation effect to enhance torque/power density (44.4Nm/L). On the other hand, by regulating the secondary windings, it achieves flexible power generation with a converter capacity requirement of only approximately 30% of the full capacity. The fundamental performance of the proposed PMVM is validated through finite element analysis (FEA). The proposed PMVM holds promise as a solution for the further development and utilization of wind energy.
