Product Description:

The MDD090B-N-030-N2L-130GA1 is a servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it turns controlled electrical power into mechanical rotation for positioning, feed, or spindle tasks found throughout industrial automation. It uses the 090 frame size and the B length code in a standard housing, and its shaft appears only on the drive side, leaving no extension on side B. That single-ended layout helps the motor fit into installations with limited rear clearance. This compact configuration supports dynamic reversal and speed regulation in demanding machine-tool and material-handling lines.

At a nominal speed of 3000 rpm, the rotor can match the output frequency of the inverter without loss of synchronism, making it suitable for processes that need rapid yet repeatable motion. When held motionless, it can supply 7.2 Nm of continuous torque, so static loads remain supported without additional gearing. The centering shoulder measures 130 mm, which aligns the flange precisely on mounting fixtures and helps maintain coaxial accuracy. Position and velocity feedback are generated through digital servo feedback, enabling closed-loop regulation down to the encoder resolution. A permanently installed shaft seal helps keep coolant or lubricants away from the bearing seats in contaminated environments.

For controlled stops and secure holding, the integrated blocking brake produces 6.5 Nm of torque, locking the rotor whenever supply power is removed. Power and feedback lines leave on side A, so cabinet wiring can remain on one face of the machine while keeping bend radii short. A keyed connector interface keeps cable attachment straightforward and helps prevent incorrect mating. The motor uses a plain shaft arrangement that accepts couplings or pulleys without additional machining, and standard dynamic balancing helps keep vibration under control.
