Design of Dual-Rotor Radial Flux Permanent-Magnet Generator for Wind Power Applications

Abstract:

Wind energy is being widely developed to replace the fossil energy and protect the environment against pollution. This paper proposes a novel dual-rotor radial flux permanent-magnet (DRRFPM) wind turbine with the toroidally-wound windings which can apparently improve the utilization coefficient of wind energy. Two concentric surface-mounted PM rotors are located inside and outside of a cup stator with back-to-back windings, respectively. The configuration, features, and design principle of the proposed machine are introduced. The magnetic circuit approach is used to analyze the machine with a simplified motor topology. To verify the accuracy of the present model, two-dimensional finite element method (FEM) is conducted for the modeled machine to validate the characteristics and performances of the proposed DRRFPM wind turbine.
