The Bosch Rexroth R911284379 (MKD112B-048-KG0-RN) is an industrial synchronous servo motor engineered for automation systems. It operates at a rated voltage between 227 and 251 V and delivers an output power range of 2.7 to 11 kW at 2800 rpm. The unit employs resolver feedback with integrated encoder, enabling absolute position detection beyond 4096 revolutions and angular precision within ±8 angular minutes. The MKD112B-048-KG0-RN features four pole pairs, a winding resistance of 0.22 Ohm at 20°C, and continuous standstill torque of 28.0 Nm, with a peak torque of 45 Nm and a rated torque of 15 Nm. The motor has a 130 mm centering diameter, natural cooling, IP65 protection class, plain shaft with a sealing ring, and a right-side power connector. The design excludes a holding brake and supports operating temperatures from 0 to +40°C. The moment of inertia is specified at 2.4 kgcm².
