ABSTRACT:
The electric generator of the present invention has a plural-section main nding; and it uses uni-directional devices to permit current to flow through various sections of that winding as the rotor poles move away from various of the stator poles of that generator but to prevent current flow through those various sections as those rotor poles approach those stator poles. By preventing current flow through those various sections, as those rotor poles approach those stator poles, the present invention relieves the field winding of all need of overcoming the magnetomotive force of that main winding. As a result, fewer ampere turns are needed to enable that field winding to provide the magnetomotive force for that main winding.
In some preferred embodiments of the present invention, an exciting winding has sections thereof that are wound on poles which have turns of the field winding wound thereon. That exciting winding responds to the magnetic lines of flux from the field winding to provide a power amplification that further reduces the number of ampere turns required for that field winding. The sections of that exciting winding are connected to the sections of the main winding to develop a D.C. exciting current in that main winding; and that exciting current enables that generator to provide a desirably-high output.
