Product Description:
The MDD071B-N-040-N2S-095PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit transforms controller output into rotary motion for indexing tables, packaging axes, and similar automation tasks. Its B-length stator and integrated feedback make it a compact actuator for multi-axis assemblies where precise torque delivery and quick speed transitions are required. It is intended for closed-loop axis control where repeatable motion is needed during frequent starts, stops, and reversals.
The motor reaches a nominal speed of 4000 rpm, allowing fast positioning cycles while remaining inside the thermal envelope of the standard housing. At standstill it can supply 4.4 Nm of continuous torque, and short stops on vertical loads are secured by the blocking brake that develops 6.5 Nm. Position data are transferred through digital servo feedback, so the drive can close a high-resolution loop without external encoders. Rotor balancing follows a standard industrial grade, and the centering pilot is dimensioned at 95 mm to support coaxial alignment with typical IEC motor flanges.
Cables exit on side B through a plug-in connector, which simplifies cabinet layouts because power and feedback harnesses share a single orientation away from the load side. This arrangement can reduce cable crowding around couplings and nearby moving parts. A factory-installed shaft seal protects the front bearing against coolant splash, allowing the housing to maintain its ingress protection without additional covers. Torque is transmitted by a DIN-profile keyed shaft with a keyway, and the single-ended design leaves no projection on the opposite face. The frame size code 071 keeps mass and inertia low, which helps the balanced rotor respond quickly to acceleration commands from the drive.
