PROBLEM TO BE SOLVED: To provide a driving device which improves heat radiation performance.SOLUTION: A driving device 1 includes: a shaft; a rotor; a stator 23; a motor part 20 including a first frame end 21 and a second frame end 22 which are located at both axial ends; and a control part 30 controlling the driving of the shaft 25. An outer wall 231 of the stator 23 is exposed between the first frame end 21 and the second frame end 22. This structure allows the stator 23 to directly contact with outer air and thus improves the heat radiation performance of the stator 23 compared to a structure where the stator 23 is covered by a motor case. |
