Product Description:
The MDD090B-N-040-N2M-130GL2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies closed-loop rotary motion to machinery that requires precise speed regulation and repeatable positioning. In automated assembly lines, material-handling stages, or packaging equipment, this unit couples directly to a drive and converts commanded current into controlled shaft torque for reliable axis actuation. Its synchronous design supports stable response during repeated start-stop cycles and coordinated axis movement.
The motor mounts against a centering boss that is 130 mm in diameter, which keeps the frame aligned with adjoining mechanics. A continuous standstill torque of 7.2 Nm allows the axis to hold static loads without overheating while the drive maintains field current. Position and revolution data come from an integrated multi-turn absolute encoder, so homing routines are unnecessary after power loss. During operation, the rotor can reach a nominal speed of 4000 rpm, making it suitable for medium-speed pick-and-place tasks and similar motion profiles. Power and feedback leads exit on the left side through a sealed connector, which simplifies cable routing and helps protect the connection point from contamination.
A blocking brake generates 11.0 Nm of static holding torque to secure vertical loads when the supply is removed, and status is reported through the built-in digital servo feedback (DSF) channel. The shaft uses a plain shaft design with a standard single-ended configuration, allowing direct coupling to pulleys or gearsets, and it comes with a shaft seal to help prevent lubricant escape and block dust ingress. Standard housing and balancing grade help limit vibration during motion. Motor size 090 and length code B set the overall dimensions, while the connector interface completes the electrical link. The absence of a side B shaft end leaves the rear face open for cooling airflow or brake access.
