INVENTORS: HANS J?RG SUTER and J?RG WILD INVENTION: DRIVE DEVICE WITH TWO MUTUALLY COUNTERACTING MOTORS FOR ELIMINATING GEARING BACKLASH ABSTRACT OF THE DISCLOSURE With small drive torque the motors counteract one another, with full-load output they act in the same sense upon the load, so that the backlash or play between the drive, the gearing and the load is eliminated. As the motors there are used compound motors whose armatures and shunt windings are connected in series. The series excitation currents are controlled by means of two 2-quadrant power adjustment or setting elements and the external excitation current is controlled by a 2-quadrant adjustment or setting element of small output. - 1 -
