The R911321550 (MSK071D-0450-NN-S1-UP1-NNNN) is a model from the Bosch Rexroth MSK servo motor series, typically used in robotics, handling systems, and machine tools. Key features include a frame size 071 and frame length D, a thermal sensor (KTY84) for protection against thermal overload, and a single-turn Hiperface interface encoder offering system accuracy of ±80 angular seconds with memory for motor type and control parameters. This promotes quick and safe motor adaptation to the drive controller. The model, rated IP65 according to EN 60529, provides full contact protection and resistance to dust and water sprays. Its housing is treated with water-based black epoxy resin coating resistant to diluted acids, alkaline solutions, water, seawater, sewage, and current mineral oils. The motor can attain speeds up to 6,000 RPM and generate 66.0Nm torque. Additionally, it features an integral holding brake with 23Nm torque to avert accidental startups, and its bearing has a nominal lifetime of 30,000 operating hours.
