Abstract
An electrical generator assembly including a central rotatable shaft () having a winding assembly () mounted thereto for rotation therewith, a rotatable permanent magnet assembly () surrounding the winding assembly () adjacent thereto and in use cooperating therewith to induce a current in the winding assembly (), and a drive system () drivingly interconnecting the central shaft () and the permanent magnet assembly (), the drive system () defining a relative rotational speed between the permanent magnet assembly () and the winding assembly () which is greater than an absolute rotational speed of the winding assembly (). A method of powering an electrical system () on a rotating rotor blade () supported by a rotating mast () is also discussed.
