R911256007
The R911256007 (MDD112B-N-020-N2M-130GA0) is an advanced digital AC servo motor, part of the MDD series, created by global leader Bosch Rexroth Indramat. Engineered for powerful, high-accuracy performance, this versatile unit is designed to be combined with intelligent digital drive controllers, enabling dynamic automation systems. Its applications extend to machine tools, textiles, and robotics, ensuring the perfect balance of speed and precision.
The R911256007 (MDD112B-N-020-N2M-130GA0) boasts a centering diameter of 130mm and sustains a nominal speed of 2,000 revolutions per minute. It delivers consistent, reliable operation, adhering to the Balance Class N per DIN VDE 0530 standards. Requiring no maintenance, this servo motor's brushless design and lifetime-lubricated bearings last for an estimated 30,000 operating hours. It has a compact design, with an impressive high power-to-weight ratio, offering flexible installation options and the potential for high radial loads. The motor uses an integrated multiturn encoder to accurately measure and store absolute indirect positions. This advanced system delivers an accuracy of ±0.5 angular minutes based on an optical measuring principle, negating the need for separate incremental encoders. Additionally, its stator features built-in thermal sensors for temperature monitoring, preventing any potential thermal overload damage. Efficiency is further ensured through effective heat dispersion from the stator to the external housing, enhancing its overload capabilities. The housing is wrapped in a robust black varnish, providing resistance against dilute acids and lyes.
