Abstract

The evolution, design and test results of a novel permanent magnet generator for use in direct-drive wind turbines are presented. This generator topology is based on steel C-core modules (which make up the rotor) and an air-cored stator winding. This topology allows a reduction in structural mass for large diameter generators, which can lead to lightweight generators.
