The Single Axially Rotating Flux generator system (SARF) uses fewer parts, and has a significantly less weight, when compared to convention dual magnet electrical generators. With the use of super strong neodymium rare earth magnets, there is no need to waste energy electrifying the field. With fewer moving parts and less weight the generator produces more power with a smaller investment.

For wind turbine applications this particular design allows for the possibility of multiple generators to be coupled inline. This offers the possibility of harnessing the power from various size blades to meet various power needs. Controlled experiments have shown that, for its size, the generator can produce roughly double the output of the common home-built generator of comparable size at less cost.
Conventional axial generators have two sets of magnets that are set opposite to each other and revolve around an armature to produce electricity. The SARF system allows for the removal of a complete set, or one rotor, of magnets while producing more power. The SARF generator produces more power than dual rotor generators with fewer parts and less weight.
When the SARF system is used for wind turbine applications, off-the-shelf automobile rotors and hubs, it eliminates the need for costly machining. The (SARF) system is more efficient, has less weight and fewer moving parts, and has a higher power density than dual magnet systems.
The new style of generator was invented in 2008 at Bowling Green State University by Mr. Charles L. Codding Jr., a past instructor in the Department of Technology Systems Engineering and currently a Process Engineer at BGSU, along with Mr. Jared Voldness, a Technology Education Student.
