As also discussed above, the need for renewable energy is increasing as traditional fuels become depleted and expensive. As noted above, flux leakage can be a significant problem for rotating electrical machines. The CFG-1 design has a prohibitive amount of leakage flux. A first version of a CFG (CFG-1) has a single permanent-magnet employed as a source of the magnetic field.

Like the CFG-1 design, however, the CFG-2 design has many issues. The rotors usually contain many permanent magnets arranged such that their poles alternate in polarity. When the stator is assembled, the north-pole conductors are interspersed with south-pole conductors and their relatively large area and small gap provide low-reluctance leakage paths for the magnetic flux.

There are 48 top magnets 5 and 48 bottom magnets 6. Letters “S” (S-pole side) and “N” (N-pole side) indicate their polarities. 1 and 2. Tubular ferromagnetic outer rotor 1 revolves around ferromagnetic inner stator 2, which has the shape of a spool with the edges serrated into a number of stator poles 3 and 4. There are 24 top poles 3 and 24 bottom poles 4. The faces of stator poles 3 and 4 move close to permanent magnets 5 and 6 attached to the inner surface of rotor 1 parallel to the axis of the machine. In certain embodiments, a PMSF device may have a ferromagnetic outer stator mounted to a shaft about a central axis extending axially through the PMSF device, a first plurality of permanent-magnets mounted in a first permanent magnet circle radially outwardly in a first transverse plane extending transversely from a first section of the central axis adjacent to an inner surface of the ferromagnetic outer stator, a second plurality of permanent-magnets mounted in a second permanent magnet circle radially outwardly in a second transverse plane extending transversely from a second section of the central axis adjacent to the inner surface of the ferromagnetic outer stator, and a ferromagnetic inner rotor coupled to the shaft.

In certain embodiments, a PMSF device may have a ferromagnetic outer stator mounted to a shaft about a central axis extending axially through the PMSF device, a plurality of top stator poles mounted in a first rotor pole circle radially outwardly in a first transverse plane extending transversely from a first section of the central axis adjacent to an inner surface of the ferromagnetic outer stator, a plurality of bottom stator poles mounted in a second permanent magnet circle radially outwardly in a second transverse plane extending transversely from a second section of the central axis adjacent to the inner surface of the ferromagnetic outer stator, and a ferromagnetic inner rotor coupled to the shaft. The ferromagnetic shaft comprises a rotor core having a core axis co-axial with the central axis, a first disc having a serrated outer edge comprising 12 top rotor poles mounted in a first rotor pole circle radially outwardly from the rotor core axis in the first transverse plane, and a second disc having a serrated outer edge comprising 12 bottom rotor poles mounted in a second rotor pole circle radially outwardly from the rotor core axis in the second transverse plane.

For example, in another embodiment, a PMSF device has 12 top poles and 12 bottom poles, as well as 24 top magnets and 24 bottom magnets. Dolor de hombro y brazo derecho . The United States Government has a paid-up license in this invention, and the right in limited circumstances to require the patent owner to license others on reasonable terms, as provided for by the terms of contract No. CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation application of U.S. Pat. No. 7,385,330, which is a continuation application of U.S. In addition, because the armature coil occupies a small fraction of the machine volume, most of which is filled with iron in order to redirect flux, the CFG-2 provides reduced power density.
