1. A motor vehicle lock comprising:
a locking mechanism,
a lock mechanism, and
an electrical setting arrangement for setting different lock states of the lock mechanism,
wherein the electrical setting arrangement has a rotor arrangement, with which a rotor and a rotor magnet arrangement for generating a rotor magnetic field is associated, and a stator, with which a stator magnet arrangement for generating a stator magnetic field is associated, wherein the stator forms at least two magnetic, unlike stator poles of the stator magnet arrangement, wherein at least one of the magnet arrangement is associated with a coil arrangement that is configured to be supplied current to generate the respective magnetic field, wherein by supplying current to the coil arrangement and a resulting magnetic interaction between the rotor and the stator, a drive torque to the rotor and thus an adjustment of the rotor is configured to be generated in a predetermined number of actuator positions,
wherein, the rotor magnet arrangement and the stator magnet arrangement are stationarily fixed to a support section of the motor vehicle lock, and wherein the rotor is pivotable about a rotor axis relative to the support section, relative to the stator magnet arrangement and relative to the rotor magnet arrangement and forms at least two magnetic, unlike rotor poles of the rotor magnet arrangement, which are respectively pivotable about the rotor axis,
wherein the electrical setting arrangement as such, when opposite current is supplied, racks in exactly two magnetically stable actuator positions by the resulting drive torque.
