The invention relates to an automobile generator with a variable speed ratio. A belt pulley is in transmission connection with an engine driving wheel, and the automobile generator comprises a generator shell, a rotor shaft arranged in the generator shell, a moving wheel and a planet wheel, and the moving wheel and the planet wheel are installed on the rotor shaft. The generator is characterized in that one side of the belt pulley is in transmission fit with the moving wheel through an electromagnetic control device, and the electromagnetic control device comprises an iron core formed in the generator shell and a coil wound on the periphery of the iron core; the moving wheel structurally comprises a meshing part used for being in transmission connection with the belt pulley, an adsorptionface making adsorption contact with the iron core in a power-on state of the coil, a low-speed contact face in transmission fit with the rotor shaft in the power-on state of the coil, and a high-speedcontact face in transmission fit with the planet wheel in a power-off state of the coil. The generator generates more electric quantity by increasing the rotating speed of the rotor when the engine is at a low speed, so that the power demand of the whole automobile is met. When a storage battery lacks electricity, the electric quantity of the storage battery is supplemented timely.
