Generator adopting magnetic rotation suspension structure

The invention relates to the field of generators, and discloses a generator adopting a magnetic rotation suspension structure, which comprises a spliced shell, a rotating shaft movably connected to the spliced shell, a stator assembly arranged in the spliced shell, a rotor assembly arranged on the rotating shaft and a driven cooling mechanism connected to the outer wall of the spliced shell, the driven cooling mechanism comprises a telescopic gas pumping assembly, a telescopic liquid pumping assembly and a telescopic liquid storage assembly, and a heat exchange assembly is arranged on the telescopic liquid pumping assembly; a driven cooling mechanism is adopted, a telescopic air pumping assembly and a telescopic liquid pumping assembly in the driven cooling mechanism can stretch out and draw back in a reciprocating mode along with rotation of a rotating shaft, cooling liquid in a spliced shell is pumped into the telescopic liquid pumping assembly in the reciprocating stretching-out and drawing-back process, m
