PROBLEM TO BE SOLVED: To provide a motor-fan capable of increasing input without shortening the service life, solving insulation problems due to brush wear powder, and minimizing oscillation. SOLUTION: In this motor-fan 3, a fan 31 covered with a fan cover 32 is fixed at a rotor shaft 21a of a motor 11 having a pair of brush devices 26, and a synthetic resin blower rectification body 13 for rectifying wind blown from the fan is disposed between the fan and stator 24 of the motor. Four stator installation projecting parts 46 are integrally provided at the back surface of the rectification body 13, and the stator 24 is screwed among the top ends of the projecting parts. The brush devices 26 are disposed between the fan 31 and the rectification body 13, and the brush devices 26 are installed at the back surface of the rectification body 13 so as to face to a rectification wind passage P of the rectification body 13. It is thus possible to restrain oscillation of the stator 24 due to magnetic field during the operation, and efficiently cool the brush devices 26 by high speed wind before reaching an armature coil 21c part of the rotator 21.
