Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a drive device which contains an electronic circuit having a choke coil, is compact, and improves the heat dissipation of the choke coil.

SOLUTION: An outer shell of a motor 30 of the drive device 1 is formed of a cylindrical motor case 103. A stator 201 is arranged inside the radial direction of the motor case 103, and a rotor 301 is arranged inside the radial direction of the stator 201. A shaft 401 rotates together with the rotor 301. The electronic circuit 50 of the drive device 1 is arranged in the direction of a central line of the shaft 401 with respect to the motor case 103. The choke coil 52 has a hole 523 at its center, and is arranged while the shaft 401 penetrates the hole.
