The invention discloses a non-chargeable and non-fuel power train. The non-chargeable and non-fuel power train realizes perpetual motion operation by adopting the stepped force application perpetual motion power principle combining step-by-step mutual force application with circular energy-complementary perpetual motion. The non-chargeable and non-fuel power train does not need external electric energy, realizes zero emission, can generate durable mechanical energy and electric power, never causes power failure and is the most complete. Meanwhile, the non-chargeable and non-fuel power train also can supply large amount of electric power to other household appliances. The non-chargeable and non-fuel power train consists of a stepped force application perpetual motion cabin, a stepped force application perpetual motion system, a deceleration control power machine, an engine, a power generator, a super-capacity storage battery and a fan. The stepped force application perpetual motion cabin comprises a perpetual motion power device inner sleeve, a casing front plate of a perpetual motion machine body, a flange plate, a casing rear cover of the perpetual motion machine, a stepped force application perpetual motion connecting shaft rod, a high-temperature resistant type axial rare earth strong magnet body, a step-by-step magnetic power and multilevel multiple-group power source device plate, a radial permanent magnet high-frequency magnet body, an air exchange ventilation cover, an integral machine base fixed bracket and the like. The non-chargeable and non-fuel power train has inexhaustible and exhaustless new energy.
