The double-rotor motor of the present invention comprises: a stator; a double rotor which is disposed with a predetermined gap at the outer surface and the inner surface of the stator; a rotor-supporting body which is formed integrally with the double rotor and is formed with a plurality of air pathways passing radially therethrough; and a heat-dissipating unit which is formed on the rotor-supporting body and forcibly blows external air to the air pathways during rotation of the rotor so as to dissipate the heat of the stator; and, as it is possible to forcibly blow external air onto the stator, it is possible to improve the stator heat-dissipating efficiency.
