Product Description:

Bosch Rexroth Indramat produces the MDD090B-N-030-N2L-110PB2 as part of the MDD Synchronous Motors series. The unit is a servo motor intended for pairing with digital drive controllers in industrial automation where precise velocity and position control are required. By generating torque directly from its permanent-magnet rotor, it drives axes in packaging lines, handling robots, and machine tools that must follow tight motion profiles. This operating principle helps the drive respond quickly to command changes during repeated start-stop motion.

The motor maintains a continuous standstill torque of 7.2 Nm, providing stable holding force under closed-loop regulation. A rated speed of 3000 rpm allows fast indexing without mechanical gear stages. The integrated blocking brake supplies 11.0 Nm of static torque to secure suspended or vertical loads when power is removed. Mounting is centered on a 110 mm pilot diameter, which helps keep couplings or gearboxes aligned during installation. Power and feedback conductors exit on side B through a connector interface, which can simplify cable routing in the cabinet. Position data is returned through digital servo feedback, enabling high-resolution commutation and automatic phase referencing. Standard dynamic balancing reduces shaft vibration at operating speed and supports smooth running.

The housing is standard cast aluminum, and its profile matches the series cooling airflow requirements. The 090 frame sets the external flange pattern, while motor length code B indicates the active stack height used for the listed torque. A single-ended shaft is provided, and the opposite face remains closed because the design does not use a second shaft extension. There is a shaft seal to limit the ingress of cutting fluids or dust, and torque is transmitted through a keyway that mates with conventional keyed hubs. This arrangement keeps the mechanical interface familiar for machines that use standard coupling elements and enclosed motor mounting.
