The invention provides an electric driving device which comprises the components of a speed reducer which is provided with two connecting surfaces which are approximately parallel, each connecting surface extends outwards to form a driving shaft, and each driving shaft is connected with a wheel; each connecting surface is connected with one motor, the air gap surfaces of the motors are parallel to the connecting surfaces, and the motors are in transmission connection with the speed reducer; and one side, deviating from the speed reducer, of each motor is connected with one controller, and the controller is electrically connected with the motor connected with the controller. The motors adopt axial magnetic field motors, and the two motors and the two controllers are arranged between two wheels with a certain wheel distance by utilizing the advantage of small axial size of the motors, so that the requirements of continuously increasing the power and torque of the motors are met, and meanwhile, the stability of the structure is ensured.
