The R911274568 (MKD090B-035-GG0-KN) is a Rexroth Indramat digital servo motor engineered for industrial automation applications requiring precise motion control. It features a plain shaft with a shaft seal, resolver feedback for relative position detection, and a nominal speed of 3000 rpm. The motor delivers a continuous standstill torque of 12.0 Nm, with a theoretical maximum torque of 43.5 Nm. Key parameters include a winding resistance of 1.90 Ohm at 20°C, a voltage constant of 111.0 V per 1000 rpm at 20°C, and a rotor moment of inertia of 43 x 10^-4 kg·m². The unit is constructed with class F insulation, optimized for operation in ambient temperatures from 0 to 45°C, and meets IP65 standards for protection against dust and water ingress. Connection is via a terminal box, and while it is supplied without a holding brake, the motor design allows for optional integration of this feature. The flange size is 140 mm with a centering diameter of 110 mm, and the motor uses maintenance-free greased bearings.
