To achieve very efficient power generation which induces total consumed energy vs. rotating speed at output branch points by using the fact that at heavy load a combined armature reaction (combined rotation resistance) of an ultra-composite generator is smaller than the armature reaction (rotation resistance) of a single generator.

An ultra-composite generator is divided into a field rotor 1, a composite superconducting bulk stator section 2, and an iron core-fixed armature section 3 to form a vacuum state 7 inside the generator. Due to this structure, a power generation mechanism by tentatively named super- electromagnetically induced induction and a power generation mechanism through electromagnetic induction are combined to cancel two armature reactions, that is, repulsion and attraction, in order to increase the cooling effect of the composite superconducting bulk stator 2.
