Wind Power Engineering Magazine: Oct 19, 2017. By Paul Dvorak. A small startup in Belgium is finalizing the development of a prototype generator, which is lighter, smaller, and more efficient than conventional designs of similar output.
Inventor and Magnax founder Peter Leijnen say his axial flux 100-kW prototype weights about 850 kg, which is significantly less than a traditional direct-drive generator that typically weighs 4,000 kg or more.
The advantages of the new technology include higher efficiency (96% to 97%, depending on the size of the machine), reliability, and scalability with relatively low production costs. While the prototype will be installed in a medium-scale, direct-drive wind turbine, Leijnen adds that Magnax’ focus is on developing megawatt-sized machines for large-scale wind turbines.
