Claim 0:
1. An electromotive actuator to adjust a height, the electromotive actuator comprising:
an electric motor with a motor shaft;
a helical gear assembly operatively connected to the motor shaft;
a sleeve-shaped friction brake to act on the motor shaft; and
a housing surrounding the electric motor or the helical gearing and including a seat of the friction brake; wherein
the friction brake includes an opening extending in a radial direction with respect to a longitudinal axis of the motor shaft such that the friction brake is attachable to the motor shaft perpendicular or substantially perpendicular to the longitudinal axis; and
the friction brake has an outer diameter which is larger than an inner diameter of the housing, in a region of the seat, so that the friction brake is seated under preload in the housing.
