PROBLEM TO BE SOLVED: To obtain a motor which achieves higher cooling effect with a simple structure and low costs, compared to a case where an existing cooling fin is provided.SOLUTION: A motor comprises: a rotor 2 having an output shaft 1; a stator 3 rotating the rotor 2; and a frame 4 thermally connected with the stator 3 and housing the rotor 2 and the stator 3. Multiple fins 5, each of which radiates heat to the atmosphere and has multiple heat radiation parts 5b radially disposed, are installed in an outer peripheral part of the frame 4 so as to be arranged along an axial direction of the output shaft 1 at an interval. |
