Lock for a motor vehicle

A method for activating a motor-vehicle lock, the motor-vehicle lock being provided with an adjusting element, which is adjustable about an adjusting element axis, and a drive for the adjustment of the adjusting element, the drive having a rotor with a permanent magnet arrangement and a stator with a coil arrangement comprising at least two coils,

• wherein the stator has at least two poles, by way of which a magnetic field generated by the coil arrangement is made to pass, in that at least one pole of the stator reaches up to the rotor to within a gap which in cross section is essentially in the form of a segment of a ring, and in that the poles of the stator are magnetically coupled by way of a conducting arrangement running around the rotor with respect to the adjusting element axis, in that an electronic control device with a logic unit is provided, in that the coil arrangement is energized in response to a signal from the logic unit and in that, for assuming at least two magnetically stable drive positions, the coils of the coil arrangement are energized in response to a signal from the logic unit in a coil combination assigned to the respective drive position, in an energizing direction assigned to the respective drive position.
