| Abstract Scope |
Improving power densities using lightweight electric generators is currently a key motivation within the wind turbine industry for reducing the costs of wind energy. However, reducing the weight of wind power generators contrasts with the principles of optimizing for lower-cost and high-volume production resulting in sub-optimal use of expensive rare-earth magnets and electrical steel. Traditional design of these machines using advanced electrical steel grades with higher saturation flux density and higher-grade permanent magnets translate to poor scaling.In this work we present results from a novel approach for light weighting the active materials in the rotor of a 15MW permanent magnet wind generator using advanced topology optimization enabled by machine learning with different compositions of additively manufactured hard and soft magnet materials. This work was supported by the U.S.Department of Energy-sponsored research program MADE3D (Manufacturing and Additive Design of Electric machines enabled by 3-Dimensional printing). |
