MDD071A-N-030-N2S-095PR2
The MDD071A-N-030-N2S-095PR2 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for connection to modern digital drive controllers, it converts regulated three-phase current into accurate rotary movement that supports coordinated motion sequences in automated assembly, packaging, and material-handling cells. Its integrated position transducer and standardized mechanical interface allow the motor to be mounted quickly and used alongside other axes in tightly synchronized production lines.
The unit reaches a nominal speed of 3000 rpm, supplying constant velocity for processes that cannot tolerate cyclical speed error. During static positioning, it can deliver 2.2 Nm of continuous standstill torque, helping prevent load creep while remaining within thermal limits. A centering shoulder of 95 mm aligns the flange precisely to adjoining machinery, easing concentricity checks after maintenance. All power, brake, and feedback conductors terminate in a single connector that exits on the right side, streamlining cable runs in cabinets positioned to the motor’s left. Closed-loop control is achieved through digital servo feedback, giving the drive high-resolution rotor angle information for dynamic error correction. Output torque is transferred through a shaft with a keyway, which mates directly with keyed hubs and helps prevent slippage under reversing loads.
Standard rotor balancing and a standard housing help minimize residual vibration during operation. Frame size code 071 and the short A length help keep inertia low, allowing rapid acceleration once the integrated blocking brake is released. That brake supplies 6.5 Nm of holding torque, securing vertical or safety-critical axes when the inverter is disabled. A fitted shaft seal protects the bearing set from coolant or dust ingress. The shaft is single-ended with no side-B extension, which helps keep the overall length short for installations with limited rear clearance.
