Abstract: A generator motor, an electric automobile and an electric ship driven by this kind of generator motor are provided. Said generator motor includes a rotating shaft (180), a generator stator (110), a rotator (120) and a motor stator (130), the generator stator (110), the rotator (120) and the motor stator (130) are installed on the rotating shaft (180) form the inner side to the outer side sequently. A generator rotator winding and a motor rotator winding are disconnected and arranged alternately on said rotator (120). The generator motor runs driven by the external electric supply, and the generating part generates electric power at the same time. The generator motor supplies the power to the electric automobile and the electric ship, which consumes the electric quantity of the storage cell (322) and supplements electric quantity to the storage cell at the same time, and the using time of the storage cell is prolonged.
