The invention discloses a hub motor with double motors running in parallel, and belongs to the technical field of hub motors. The motor comprises a direct-drive motor and a low-torque motor. The direct-drive motor is used for directly driving wheels, the direct-drive motor and the low-torque motor share one cooling system, and power of the low-torque motor is input to a first-stage planetary reduction mechanism. Whether power is transmitted from the first-stage planetary speed reducing mechanism to the second-stage planetary speed reducing mechanism or not is determined by attraction and separation of the clutch, power of the third-stage planetary speed reducing mechanism is coupled to an outer rotor shell of the direct-drive motor through an outer transmission cover, and parallel operation of the double motors is achieved. The direct-drive motor adopting the design runs for a long time, so that the hub motor has a series of advantages brought by direct drive, such as high efficiency, high reliability and fast system response, and a low-torque motor transmission chain provides short-time torque at a relatively large speed ratio, so that the torque requirements of vehicle climbing and medium-low speed acceleration can be met, and the limitation of the direct-drive motor is solved.
