The R911277049 (MKD112B-073-KG0-AN) servo motor is part of the MKD series by Bosch Rexroth and is a synchronous digital motor designed for durability with a chemically resistant black coating and optional 40 μm varnish. It incorporates a friction-locked plain shaft and a chemically and oil-resistant radial shaft sealing ring that requires proper lubrication. The motor features a resolver feedback system with integrated multiturn absolute position detection exceeding 4096 revolutions. It is surface-cooled, supports both radial and axial blower configurations, and is equipped with side A parallel connection. The shaft and bearings tolerate combined axial and radial loads and, per DIN ISO 281, the bearing lifespan is rated at 20,000 hours within specified load limits. The R911277049 operates with a continuous standstill torque of 28.0 Nm, a nominal voltage of 115V, and a nominal current of 13A. The motor measures 200 mm in height, corresponds to motor length B and size 112, and does not include a holding brake or alternative designs.
