The invention realizes that the concentric nested double-rotating shaft is used as the shaft extension of the composite generator in a radial composite mode, the concentric nested double-rotating shaft extension can realize that the independent shaft extension of any generator in the composite double-generator is driven to generate electricity, and can also realize that the inner shaft extension and the outer shaft extension of the double-generator are simultaneously driven by external force to generate electricity. The three power generation output modes can provide various output selections of the same or different combinations of generated power, and provide various selections of power generation types such as alternating current and direct current, high voltage and low voltage, and the like. The novel multi-combination power generation output mode can provide equipment for the generator to provide rotary power, such as further intellectualization of an internal combustion engine, higher efficiency, energy conservation, environmental protection and multiple purposes, provides a new solution, and also provides a new basic condition for the application of multiple purposes of the generator.
