Abstract

Through the comparative study of the TORUSNN and TORUS-NS topologies for the axial flux permanent magnet synchronous generator (AFPMSG), it is shown that the AFG with single stator double rotors topology is suitable for vertical axis wind turbines (VAWT). The basic parameters are designed and their 3D finite element models are established for the two topologies, which are compared and analyzed respectively on the same amount of magnets and windings, the magnetic density, THD value, torque ripple and efficiency. The research shows that the efficiency of TORUS-NN structure is only 0.22% higher than that of TORUS-NS structure with the same amount of magnetic steel, but the torque ripple of TORUS-NN structure is much greater than that of TORUS-NS structure, when the amount of magnet steel and the winding are the same, the efficiency of TORUS-NS structure is 8.5% higher than TORUS-NN structure. Considering their performance and economy, the TORUS-NS structure is superior to TORUS-NN topology structure for VAWT in starting torque and low wind speed. The experimental results and finite element analysis results are within the allowable error range, which verifies the feasibility and superiority of TORUS-NS topology for VAWT.
