The invention belongs to the technical field of motors, and particularly relates to an easily-cooled motor, which comprises a motor shaft, a stator, a rotor, a shell, a base, a spiral pipe, an air deflector and a compression module, wherein the compression module comprises a cam, expansion cylinders, an air pipe, drying chambers and check valves; the spiral pipe is rotationally arranged on the outer circle of the shell; the spiral pipe is set to be a diameter-varying pipeline, and the bottom pipe diameter of the shell is 2 to 3 times that of the top; the top part of the shell is provided withan axial through hole connected with the spiral pipe, and the through hole is communicated with the air deflector; the air deflector is arranged at one end inside the shell; and air is added to cool the motor along the spiral pipe, in match with the air deflector, the dried air is inputted in the motor, and the inner part of the motor is cooled. The easily-cooled motor is particularly suitable forbeing used in a humid environment, vapor in the air is used to be liquefied to cool the motor, the air is blown in the motor after being dried thoroughly, the cooling efficiency is improved, vapor can be prevented from entering the motor, and the service life of the motor is improved.
