1. A feedback actuator for a steering device of a motor vehicle, the feedback actuator comprising:
a casing unit having
an outer casing that is attachable to the motor vehicle, and
an inner casing that is received in the outer casing such that the inner casing is telescopically adjustable in a longitudinal direction;
a steering spindle mounted in the inner casing such that the steering spindle is rotatable about a longitudinal axis; and
an electric motor of a drive unit disposed in an interior space of the casing unit,
wherein the electric motor includes
a stator that is fixed on the outer casing, and
a rotor that is configured to be driven rotationally and has a rotor shaft that is coupled via a gear mechanism to the steering spindle;
wherein the electric motor has an outer s section that is smaller than an inner cross section of the inner casing.
