Abstract

Provided are: a motor device capable of adjusting the rotation balance of a rotor while suppressing an output torque reduction or the like; and a method for manufacturing the same. A rotor 33 equipped with a rotating shaft 34, a rotor core 33a fixed to the rotating shaft 34, a magnet MG fixed to the rotor core 33a, and an adjustment member 37 which is fixed to the rotating shaft 34 and adjusts the rotation balance of the rotor 33, wherein the separation distance L1 between the magnet MG and the adjustment member 37 in the axial direction of the rotating shaft 34 is greater than the separation distance L2 between the magnet MG and the stator 32 in the radial direction of the rotating shaft 34 (L1>L2). As a result, the rotation balance of the rotor 33 can be adjusted, and the adjustment member 37 can be positioned farther from the magnet MG than is the stator 32. Thus, movement of the magnetic flux [Wb] from the magnet MG toward the adjustment member 37 is suppressed, and is efficiently directed toward the stator 32.
