PROBLEM TO BE SOLVED: To offer a low-speed motor which can be made compact without lowering its efficiency. SOLUTION: In this low-speed motor 1, a rotor 3, which is equipped with a rotating shaft 3a and a rotor yoke 3b provided coaxially with the rotating shaft 3a, and a stator 4, which is arranged outside this rotor 3, are stored in a casing 2. This motor is equipped with fans 10 and 11 for cooling the rotor 3 and the stator 4 by letting fluid flow to a gap 9 made between the rotor 3 and the stator 4, being attached to at least axial one end of the rotor yoke 3b, and a differential gear device 6 for decelerating the rotational speed of the rotating shaft 3a and outputting the rotational speed to an output shaft 5.
