Product Description

Bosch Rexroth’s MDD servo motors deliver high torque and acceleration in a compact unit. They are high-performance servo motors built to suit a wide range of applications by their flexibility and impressive features. These applications include textile machines and robotics.

The MDD093B-F-040-N2L-110PR1 is a compact MDD servo motor featuring electronic commutation. It reduces the risk of wear and tear in the motor since there are fewer mechanical parts, improving its overall reliability. This feature also gives the motor a high cyclic load capacity, meaning that it can withstand repetitive loads and forces over a long period. As a result, it is ideal for continuous start-stop operations with high repetitive frequencies. It also reduces the risk of downtime and improves the motor’s performance. The MDD model can reach a nominal speed of 4,000 revolutions per minute and has a centering diameter of 110mm. Its holding brake has a holding torque of 11.0Nm and holds the servo axes when it is disconnected from power.

Dynamically balanced in terms of Balance Class R per DIN VDE 0530, the MDD093B-F-040-N2L-110PR1 supports demanding applications like grinding machines. It has an output shaft with keyway in line with DIN 6885-1, providing a secure and precise form-fitting torque transmission. The shaft type also reduces wear and tear on the shaft since it even distributes the torque across the load, reducing stress concentration. Its sealing ring prevents fluids from penetrating the motor through the shaft. A thermal sensor in the windings of this MDD model monitors its temperature and prevents irreversible damage due to overheating. Its feedback type is digital motor feedback, using the optical measurement principle to evaluate its relative indirect position.
