The present servomotor has a working piston in a piston cylinder. The working piston is connected to a spindle having a relatively high pitch. The spindle is attached at one end thereof to a control disk system comprising three control disks. The two outer control disks are rigidly connected to the spindle, and the central control disk is connected to a digital stepping motor. The central disk is arranged between the two outer control disks so that the central disk may rotate substantially free of play, whereby the rated position of a stepping drive motor corresponds precisely to the actual position of a linear output member, such as a piston rod.
