Abstract
An electromotive servo drive includes a drive motor having an external rotor and a drive train in driving relationship with the drive motor and having an output member operatively connected to a control element to be adjusted. A locking device having a brake element is movable between a release position in which the rotor is free to rotate and an operative position in which the rotor is locked in place. Operatively connected to the brake element is a reset spring for maintaining the rotor at a standstill, when the reset spring is under tension, wherein the reset spring tensioned by turning an actuating shaft by hand.
