The R911293921 (MKD112D-027-KP0-RN) is a Bosch Rexroth MKD series servo motor featuring a brushless, maintenance-free design with grease-lubricated bearings. The flange conforms to DIN 42948 for straightforward machine integration. It weighs 56 kg and utilizes Class F (thermal class 155) insulation in line with DIN VDE 0530 Part 1. The motor provides a continuous standstill torque of 48.0 Nm, operates within a 200-400 V range at a rated current of 29.5 A, and does not include a holding brake. It uses a resolver with integrated encoder for absolute position detection greater than 4096 revolutions. The shaft features a keyway and shaft seal, with a centering diameter of 130 mm and motor size 112 (length D). The device offers IP65 protection and is compatible with GTP and GTS planetary gearings. Installation below 1,000 m sea level is recommended. This servo motor is intended for industrial automation and should not be used in elevators, construction cranes, or refinery plants. Entry to hazardous areas should only occur when the drives are stationary. Power and feedback connections use dedicated connectors.
