Abstract
An adjustment drive for a motor-adjustable steering column for a motor vehicle, includes a spindle drive having a threaded spindle which engages in a spindle nut which, so as to be able to be driven in a rotating manner about the spindle axis relative to the threaded spindle, is coupled to the rotor shaft of a drive motor which has a rotor and a stator. In order to enable a compact design with minor complexity, the rotor shaft of the drive motor is configured as a hollow shaft which is disposed so as to be coaxial with the spindle axis and in which the threaded spindle is coaxially disposed.
