R911256238
The R911256238 (MDD112B-N-020-N2M-130PA0), a creation of Bosch Rexroth Indramat, is part of their highly versatile MDD AC servo motor series. These permanent magnet-excited synchronous motors, boasting an array of functionalities, pair seamlessly with Bosch Rexroth's intelligent drive controllers to form efficient automation systems. Applications of these motors span multiple sectors including tooling, textiles, printing, packaging, robotics, and handling equipment among others.
The R911256238 (MDD112B-N-020-N2M-130PA0) variant comes with a digital servo feedback mechanism and an incorporated multiturn encoder, enabling absolute indirect position evaluation on the motor with an impressive system accuracy of ±0.5 angular minutes. Its output shaft, designed for form-fitted torque transfers, simplifies installation along with its ready-made cables. The motor likens to a high overload-capable machine due to effective heat conduction towards its outer housing wall, while a built-in temperature sensor offers protection from thermal overload. Its black prime-coated body is able to resist weathering, yellowing, chalky build-ups, diluted acids, and alkalis. This fully contained motor, rated IP 65, guards against solid object intrusion and water jet damages. The motor's bearing can withstand lofty radial loads and sports an impressive lifetime of 30,000 operating hours. Optimal operation conditions suggest an ambient temperature of 40°C, relative humidity of 95%, and an elevation of 1000m.
