Abstract:
1. A starter/generator machine for a turbine with a turbine enclosure, an air duct, and a plurality of fan blades within said air duct, said starter/generator machine comprising a plurality of stator elements spaced at intervals in a ring shape adjacent to said air duct, wherein each of said plurality of stator elements is shaped to minimize air flow interference and is mounted to interact magnetically with each era plurality of rotor elements to exert a force sufficient to move said rotor elements, wherein each of said plurality of rotor elements is mounted on said fan blades inward of a tip of the fan blades in a location selected to interact magnetically with each of said stator elements, wherein each of said plurality of stator elements is formed with a core, at least one pole, and multiple windings and each of said rotor elements is spaced a distance from each of said stator elements to form an air gap on the order of 5-10 mm, and wherein the number of said stator elements is different from the number of said rotor elements.
