Abstract
A motor vehicle lock having a positioning element, especially a control shaft, and a drive unit for moving the positioning element, wherein the drive unit has a rotor and a stator, the stator having a coil arrangement and at least two magnetically conducting poles associated with the coil arrangement for conducting the magnetic field created by the coil arrangement. It is proposed that the poles each time form, with the rotor, an axial air gap relative to the geometrical rotor axis, possibly in dependence on the rotor position, and a first segment of the coil arrangement with at least two coils and a second segment of the coil arrangement with at least two coils are arranged along the geometrical rotor axis on opposite sides of the rotor.
