R911250933
The R911250933 (MDD093B-N-040-N2L-110GB0) is a digital AC servomotor developed by Bosch Rexroth Indramat, designed to complement a digital drive controller seamlessly. Noted for its high power density, the motor is ideally equipped for high-speed cutting applications. Endowed with a thermal stress-resistant, plain shaft, the motor also includes digital servo feedback for improved precision. This unit also includes lifetime-lubricated bearings and an integrated temperature sensor to mitigate potential overload damage. High synchronization levels are achieved due to the sinusoial application of current and remarkable motor feedback resolution.
Encased within housing that facilitates natural convection and surface cooling, the R911250933 (MDD093B-N-040-N2L-110GB0) also boasts the capacity for water ingress protection. Its lateral axis acceleration amplitude reaches a maximum of 20m/s2 with sinusoidal oscillation. It uses a non-positive shaft-hub connection and allows the B14 design mounting via a threaded mounting flange. Notably, the motor features a standard 110mm pilot diameter and non-positive, backlash-free torque transmission. It also requires shaft sealing in water or dirt-prone applications. The unit is also equipped to handle a 36.6A continuous current in standstill mode, even with natural convection cooling measures.
