The R911283537 (MKD112C-024-GG3-BN) is a synchronous servo motor by Bosch Rexroth, configured with a plain shaft, shaft seal, and a 70 Nm holding brake for servo axis clamping during deceleration. It features a resolver (RSF) for relative position detection and digital feedback. The motor is designed for natural convection cooling with an optional blower attachment. Its characteristic speed is 2000 rpm, delivering a continuous torque range of 38 to 57 Nm and rated power from 5.2 to 14.1 kW. Operating within a thermal range of 0 to 40°C and up to 1000 meters altitude, the model runs on a 372 to 404 VAC supply at 26.6 to 39.9 A. The inertia is specified at 273 × 10⁻⁴ kgm². The housing has a black, weather-resistant coating and bears an IP65 protection degree. The servo motor employs lifetime lubricated bearings and PTC thermistor-based thermal protection. Motor size is 112 mm with centering diameter of 130 mm, length C, and connections oriented to side B.
