Abstract
A device for moving a movable structural component with respect to a stationary structural component includes a first fastening element which can be fastened to the movable structural component, and a housing tube having a second fastening element which can be fastened to the stationary structural component. A spindle drive for moving the first fastening element axially relative to the housing between an extended position and a retracted position includes a spindle nut arranged on a threaded spindle. An electric motor arranged in the housing tube drives one of the spindle nut and the threaded spindle in rotation. A power supply for supplying power to the electric motor includes a power output stage arranged in the housing tube, wherein the power output stage is shielded from electrical and magnetic fields.
