R911270048
The Bosch Rexroth Indramat R911270048 (MDD112C-N-030-N2L-130GA3) is a robust digital AC servomotor designed with a compact build, high contouring accuracy, and fast feed rate. Storage for this motor should be in a dry, horizontal orientation to prevent damage. Equipped with permanent magnets, two M8 tapped holes in the housing, and spigot nuts on its connectors, this motor is an essential part of grinding machines. Also, it’s capable of supporting electronic commutation for its maintenance-free operation. The design incorporates a laminated core for the magnets, fixed and floating bearings, a plain output shaft, and a protective housing according to DIN 40 050 specifications, ensuring an IP 65 degree of protection.
Designed to operate between 0°C and 45°C, the R911270048 (MDD112C-N-030-N2L-130GA3) is versatile for both horizontal and vertical installations. Adaptable for coupling with belt pulleys and pinions through pressure sleeves, this unit’s thermal length deformations are minimally disruptive. A notable feature is its ability to use both radial and axial surface cooling. The device comes with a 60Nm blocking brake that is driver-controller activated, requiring reseating running approximately at a speed of 100RPM. Moreover, the motor's reliable performance is ensured with a maximum 0.3mm excursion amplitude for its longitudinal axis.
