Product Description:

The MDD025B-N-100-N2K-040FF0 is a Bosch Rexroth Indramat synchronous servo motor in the MDD Synchronous Motors series and intended for digital drive controllers in compact automation axes. As a motor for closed-loop positioning, it converts electrical power from the associated drive into mechanical rotation. It is suited for pick-and-place modules, small conveyors, or tool-handling stages that need rapid speed changes and precise feedback.

The unit delivers a continuous standstill torque of 0.60 Nm, supplying enough holding force for lightweight loads without exceeding the thermal limits of its B-length frame. A rated velocity of 10000 min⁻¹ allows high surface speeds when paired with gearing or direct-drive spindles. Its rotor is manufactured with standard balancing, minimizing vibration when the 025-size housing clamps to machinery through the centering pilot. That interface measures 40 mm to match Rexroth flange patterns. Mechanical arresting is not integrated, and the motor is supplied without a blocking brake, so external holding mechanisms or drive torque must secure vertical axes during power-off. The plain aluminum housing follows the standard enclosure style, and it omits a shaft seal to reduce friction when the coupling area is already protected. A connecting cable with a molded coupling unit links power and feedback lines to the controller.

Position data reaches the drive through resolver feedback, while multi-turn position retention is provided by an integrated absolute encoder. Together, these devices let the controller read the exact rotor angle after a power cycle. The output end uses a plain shaft with no side-B extension, making direct coupling possible in confined spaces. Electrical and sensor conductors exit on the machine's right flank, and these right-side connections align with cabinets laid out for serial mounting. Balancing, housing, and motor length code B remain standard across the model.
