Abstract: An operating device according to the present invention includes magnetic field generation means. The magnetic field generation means includes a coil generating a magnetic field when energized, and a yoke forming a magnetic path for the magnetic field passing through a rotor. A control unit includes magnetization means and rotational torque control means. The magnetization means supplies a current to energize the coil such that a residual magnetic field in the yoke is held at a predetermined magnitude. The rotational torque control means adjusts a current value applied to the coil in accordance with the magnitude of the residual magnetic field in the yoke. An absolute value of a maximum value of the current value applied to the coil by the rotational torque control means is smaller than an absolute value of a current value applied by the magnetization means.

Abstract: In an operating device, a brake setting unit sets a target braking torque based on a braking torque pattern, and a rotational torque setting unit sets a target rotational torque based on a rotational torque pattern in accordance with information detected by a rotation detecting portion at reference time intervals. A control unit includes a time change adjustment unit. For at least one of the braking torque and the rotational torque, the time change adjustment unit changes the braking torque so that a current braking torque reaches the target braking torque and/or changes the rotational torque so that a current rotational torque reaches the target rotational torque in a predetermined time period greater than the reference time interval.
