Product Description:

The MDD112B-N-030-N2L-180PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated DC-link energy into precise rotary motion required by indexing tables, pick-and-place units, and other automated stations. Its construction integrates sensor feedback and standardized mounting features so it can be fitted into multi-axis systems that require accurate speed control and repeatable positioning.

The motor centers itself on a 180 mm centering diameter, permitting rigid flange coupling to heavy gearboxes or machine frames. The power and feedback connectors are routed rearward because the connection is on Side B, which keeps the front face clear for close-coupled loads. At stall, it supplies 17.5 Nm of continuous torque, allowing static load support while remaining within the thermal limits of its standard cast housing. Under command, it reaches a nominal speed of 3000 rpm, accommodating machine cycles that require rapid indexing and smooth acceleration. Rotor position is delivered through digital servo feedback (DSF), so the drive can generate smooth sinusoidal currents and maintain stable closed-loop control. The electromagnetic package follows motor size 112, and the length code B marks the second-shortest stack, which helps balance inertia and torque capacity. Standard balancing helps reduce vibration, and the winding leads terminate in a sealed connector for straightforward cable connection.

The housing is supplied with a shaft seal, which helps keep dust or fluid from migrating along the output journal. The steel shaft features a keyway and has no auxiliary extension on side B, matching the standard shaft-end arrangement used for this motor style. The motor is delivered without a blocking brake, so load holding during power loss must be provided by the drive or by external mechanical means when the application requires it. A standard housing finish and balanced rotor support operation in typical industrial settings, while the connectorized wiring keeps the external electrical connection clean and compact.
