In an electric motor (39) a rotor (41), placed inside or outside of a stator (40) in the radius direction, includes a fixed rotor (42) fixed in a position along a rotation axis of the rotor (41), and a movable rotor (43) allowed to approach/separate from the fixed rotor (42) and to move in a direction along the rotation axis. In such an electric motor (39) the accuracy control is facilitated, the amount of magnetic flux is able to be changed, and variation in products has less effect. |
