The R911270670 (MDD093A-N-030-N2L-110GB2) is a synchronous servo motor from the MDD series by Bosch Rexroth designed for automation systems like robotics and handling systems. This maintenance-free servo motor features a brushless design and lifetime lubricated bearings, along with electronic commutation, making it suitable for high repetition start-stop operations. The motor also supports high radial loads, allowing pinions and belt pulleys to attach directly to the shaft. It belongs to Balance Class N with a centering diameter of 110mm and cools by natural convection and surface cooling. Sealed in a sturdy housing, it has an IP 65 rating, indicating it is touch-proof, dust-proof, and water resistant. Additionally, it includes a digital servo feedback system for motor position evaluation, removing the need for incremental encoders. This servo motor has a speed of 3,000 RPM, a maximum torque of 28.6Nm, rotor inertia of 22 x 10-4 kgm2, and peak current rating of 79.9A.
