摘要

The motor has an electric motor with a rotor (1), which is connected with a threaded spindle. Threads of the spindle stay in contact with a thread of a spindle nut that is connected with a piston rod (13). The nut is axially guided with the piston rod into a casing (3) of the electric motor. The spindle is supported with the rotor in the casing, and a guide part is connected with the spindle nut and the piston rod for axially guiding the guide part. A guidance part is axially guided in the casing over slots, which are axially movably arranged in a groove of the casing.
