The Bosch Rexroth Indramat R911257704 (MDD112C-N-030-N2M-130GA0) is a servo motor from the MDD 112 family, designed specifically for high precision and synchronization tasks in digital drive controllers. Weighing around 103 pounds, this motor provides a nominal speed of 3000 rpm and does not come with a blocking brake. It boasts a normal balance class, making it suitable for regular applications, a digital servo feedback with an integrated multi-turn encoder to maintain absolute axis position when powered down, and its power connection is situated on side A. Additionally, the motor features a 130mm standard centering diameter, a plain dust and water-resistant shaft for non-positive hub connections, and offers excellent dynamics due to its favorable torque-to-inertia ratio. It works optimally between 0 to 45 degrees Celsius, and through its standard housing, it promotes natural convection and surface cooling, with an in-built temperature sensor to avoid overheating.
