A movable body portion Sm is configured to reciprocate in a rotation angle range Zm between a first position Xa and a second position Xb according to energization control of a driving coil 6 and to be stopped at the first position Xa and the second position Xb by a pair of self-holding mechanisms 11a and 11 b by restriction of a pair of restricting stopper mechanisms 10a and 10b and attraction of magnets 8a and 8b. when controlling switching from the second position Xb (or the first position Xa) to the first position Xa (or the second position Xb), after a driving voltage based on a driving pulse Ps is applied to the driving coil 6, if the movable body portion Sm has reached a predetermined intermediate position Xp in 10 to 50 [%] of the rotation angle range Zm, control is performed so that application of the driving voltage is stopped.

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.

The disclosure relates to a vehicle lock having a locking mechanism, a lock mechanism and an electrical setting arrangement, wherein the setting arrangement has a rotor arrangement, and a stator, wherein the stator forms at least two magnetic, unlike stator poles of the stator magnet arrangement, wherein at least one of the magnet arrangements is associated with a coil arrangement, wherein by supplying current to the coil arrangement and a resulting magnetic interaction between rotor and stator, a drive torque to the rotor and thus an adjustment of the rotor can be generated in a predetermined number of actuator positions. Proposed is that the rotor magnet arrangement and the stator magnet arrangement are stationarily fixed to a support section of the motor vehicle lock, and the rotor is pivotable about a rotor axis relative to the support section and relative to the rotor magnet arrangement.
