Abstract— Renewable energy has been the topic of much research over the years. Wind power generation, categorized as a direct drive application, requires a low-speed and high-power density generator. The permanent magnet Vernier machine is one of the flux modulation ones which can have both features simultaneously. The axial flux structure can be a better solution for this application instead of the radial counterpart with having more power density, efficiency and compact structure. So, in this paper, a 300W axial flux permanent magnet Vernier generator TORUS type for wind power generation is investigated. with NN type magnet structure, the toroidal winding configuration is used and consequently, end winding connection is descended. The phase voltage and volume of the machine is formulated. Then, the proper decision variables and primary design considerations are discussed. Using genetic algorithm, the volume of the machine is optimized subjected to the constant phase voltage with MATLAB software. Finally, the optimization is simulated using 3D-FEM and flux density, no-load phase voltage with harmonic orders and voltage regulation are analyzed. The final design power density reached 196 kilo Watt per cubic meter. In addition, a low value in THD resulted, which is desired for the wind turbine.
