The invention discloses a generator structure of an extended-range electric vehicle. The generator structure comprises a rotor iron core and a stator iron core. The rotor iron core is adhered to a rotor iron core support in a sealed manner. The central position of the rotor iron core support is connected with an engine shaft through a bolt. The engine shaft is inserted into the center of the shell. The inner side wall of the shell is connected with the stator iron core through a bolt. According to the invention, the shell is directly mounted on the end cover of an engine; a rotor iron core assembly composed of the rotor iron core and the rotor iron core support is directly connected with the engine shaft; an original engine mass flywheel and a gear ring assembly are cancelled; a generatorrotor is used for replacing the mass flywheel and the gear ring assembly; the requirement of the engine for inertia of the flywheel is met; the requirement of the engine for vibration, rotating speedfluctuation and the like is met; the whole rotor assembly is supported through the rear end cover and a bearing; the rotor does not generate eccentricity generated by structural deformation; and the eccentricity and control precision of the rotary transformer rotor and stator are guaranteed.
