A dual-rotor wing motor includes a sleeve separating an inner shaft from an outer shaft. An external bearing is independently coupled to a shaft cover while an internal bearing is independently coupled to the inner shaft, and thus the external bearing and the internal bearing independently bear a friction force due to the rotation of the respective single shaft, the heat generated by the friction force can be reduced and the lubricant cannot be easily evaporated. Accordingly, the service life of the dual-rotor wing motor of the present invention can be prolonged.
