Provided is a double-rotor type motor including: a stator; a double-rotor that is positioned at a certain gap on an outer surface and an inner surface of the stator; a rotor support on which the double-rotor is integrally formed and a plurality of air passages are radially penetratively formed; and a heat dissipation unit that is integrally formed with the rotor support and that forcibly ventilates outer air into the air passages during rotation of the rotor, to thereby dissipate heat generated from the stator. Thus, outer air may be forcibly ventilated to the stator, to thereby improve the heat dissipation efficiency of the stator.
