The invention belongs to the technical field of generation, transformation or distribution equipment, and discloses a rapid cooling motor. The rapid cooling motor comprises a casing, a stator and a coil, the stator is connected with a commutator and a brush, sidewalls of the casing are provided with small holes, a heat conducting portion, a sliding portion and a heat radiation portion are arrangedin the casing, the heat conducting portion comprises a first piston and a second piston of a heat conducting cylinder, inert gas is injected between the first piston and the second piston, the sliding portion comprises a first wedged rod and a second wedged rod, one end of the second wedged rod is hinged to a baffle, the baffle is provided with a plurality of radiating holes, the heat radiation portion comprises a push rod, an installing plate and a slide rod, one end of the slide rod is provided with a limiting block, a torsion spring is arranged between the limiting block on the slide rod and the installing plate, the slide rod is provided with a rotating rod, two ends of the rotating rod are respectively provided with a block, the block is provided with a first magnet, the other end ofthe slide rod is provided with a rotating blade, and the bottom of the casing is provided with a second magnet. According to the rapid cooling motor, the problem that in the prior art, the cooling effect is poor since external air does not easily enter the casing in a wind-free environment is solved.
