R911252990
Produced by Bosch Rexroth Indramat, the R911252990 (MDD112C-N-030-N2L-130GL1) is part of the renowned MDD series of synchronously operating servo motors, and is designed to provide reliable and efficient operations in automation systems. The permanent magnet-excited motor is ideally suited for use in machine tools and robotics, having been deployed with impressive success rates.
The R911252990 (MDD112C-N-030-N2L-130GL1) AC servo motor boasts a nominal speed of 3,000 rpm and a rotor's moment of inertia of 170 x 10-4 kgm2. The motor can withstand high cyclic load due its electronic commutation attributes, making it perfect for sustained start-stop functions with significant repetition rates. Notably, the motor has a brushless form and self-lubricating bearings, which facilitate maintenance-free operations. It also incorporates a thermal sensor in its stator windings for temperature regulation, further enhancing its protection from thermal overload. The product’s entirely enclosed housing has an IP 65 rating as per EN 60529, making it suitable for use in challenging environmental conditions. A torque of 14.0Nm blocking brake ensures the servo axis holds steady when power is turned off. Other features include plain shaft with a shaft sealing ring for backlash-free and torque transmission, and heat dispersal via surface cooling and natural convection. This model's centering diameter is 130mm, and it can produce a theoretical maximum torque of 100.4Nm.
