The R911318178 (MKD112B-048-GG2-BN) is an MKD112 series Bosch Rexroth servo motor engineered for industrial automation. It features a nominal speed of 3000 RPM and a primary speed of 3500 RPM, with a maximum speed capability of 4500 RPM. The motor supplies 28 Nm continuous torque at 60K overtemperature, increasing to 33 Nm at 100K, with corresponding continuous currents of 35.6 A and 43.5 A. It has a torque constant of 0.88 Nm/A and a voltage constant of 80 V/1000 RPM. Structural details include a plain shaft with keyway, main shaft seal, and a 32 Nm holding brake. The motor incorporates resolver feedback for relative position detection and is enclosed in a housing rated to IP65. Additional specifications include a 192 mm flange size, 130 mm centering diameter, 56 kg weight, 0.057 kgm² rotor inertia, and 40-minute thermal time constant. Recommended wire size is 6 mm². Connection is via Side B and the motor operates optimally at 20°C ambient temperature.
