R911245767
The R911245767 (MDD090C-N-030-N2L-130PB0), developed by Bosch Rexroth Indramat, is a high-performance device that brings together dynamic digital drive controllers and robust servo motors from the MDD series. This combination enables the creation of quick-reacting automation systems suitable for diverse machinery including robotics, machine tools, and machines used in textile, paper processing, and printing sectors. Particularly, MDD motors are highly suited for high-speed range cutting applications.
The R911245767 (MDD090C-N-030-N2L-130PB0) belongs to the MDD series of synchronous motors, featuring a permanent magnetized rotor made from rare earth materials and iron oxide, which contributes to a low-inertia motor construction. Notably, this construction results in an ideal torque-to–inertia ratio for high dynamic operations. The device also incorporates thermal sensors in its windings and a shutdown mechanism ensuring protection from thermal overload. A natural convection and surface cooling process dispels the motor-generated heat and permanently lubricated bearings designed for high radial loads enable direct attachment of pinions or belt pulleys to the motor shaft. The R911245767 (MDD090C-N-030-N2L-130PB0) model delivers a maximum torque of 56.3Nm at a nominal speed of 3,000 rpm. It comes with feedback via a digital servo and a data storage feature. The feedback encoder offers system accuracy within ±0.5 angular minutes. Additionally, it uses optical measurement for speed and position tracking, and the motor shaft incorporates a sealing ring and follows the DIN 6885-1 standard keyway design.
