A starter/generator machine for a turbine with a turbine enclosure, an air duct, and a plurality of fan blades is provided. The starter/generator machine includes a plurality of stator elements spaced at intervals in a ring shape adjacent to the air duct and a plurality of rotor elements mounted on the fan blades. The stator elements and the rotor elements are mounted to interact magnetically to exert a force sufficient to move the rotor elements. The stator elements are shaped to minimize air flow interference and are formed with a core, at least one pole, and multiple windings. The spacing between the stator elements and the rotor elements forms an air gap on the order of 5-10 mm, and the number of stator elements is different from the number of rotor elements.

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. 2. The machine of claim 1, wherein said rotor elements are constructed from a soft magnetic material and said fan blades are formed so that said rotor elements are integral to said fan blades. 3. The machine of claim 1, wherein said stator elements have salient poles facing said fan blades and said rotor elements, thereby forming a ring motor. 4. The machine of claim 1 wherein each of said rotor elements comprises a ferro-magnetic flux guide and each of said stator elements is a ferro-magnetic core that is C-shaped, U-shaped, or bar shaped. 5. The machine of claim 1, wherein each of said rotor elements is mounted on a tip of a fan blade. 6. The machine of claim 1, wherein said rotor elements and said stator elements form a switched reluctance motor, a permanent magnet DC motor, a synchronous induction motor, or an asynchronous induction motor. 7. The machine of claim 6, wherein the motor formed by said stator elements and said rotor elements has at least two phases per pole. 8. The machine of claim 1, wherein said air gap is less than 5 mm. 9. The machine of claim 1, wherein a stress compensation ring is located at an outer periphery of said fan blades. 10. The machine of claim 9 wherein said rotor elements are also mounted to said stress compensation ring. 11. The machine of claim 1, wherein said machine generates power. 12. The machine of claim 11, wherein said machine powers a car, a boat, an aircraft, or other vehicle. 13. The machine of claim 1, wherein said plurality of fan blades are compressor blades or expansion blades.
