The utility model provides a double-rotor motor which comprises an inner rotor assembly, a motor stator and an outer rotor assembly, a first tooth crown is arranged along the inner ring of the circumference of the motor stator in an outward extending mode, and a second tooth crown is arranged along the inner ring of the circumference of the motor stator in an inward extending mode. The inner rotor assembly comprises a rotor iron core and a first permanent magnet embedded in the rotor iron core, an inner rotor shaft is fixedly arranged in the rotor iron core in a penetrating mode, and the outer rotor assembly comprises a rotor iron ring wrapping the outer side of the motor stator and a second permanent magnet fixed to the inner wall of the rotor iron ring. And an outer rotor shaft is sleeved in the rotor iron ring. By arranging the inner rotor assembly and the outer rotor assembly, better torque and higher rotating speed can be output outwards under the general power-on condition, so that a larger load can be
