MDD071A-N-040-N2T-095PR1
The MDD071A-N-040-N2T-095PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for pairing with digital drive controllers to deliver controlled speed and position in automated assembly stations, handling modules, and packaging axes where compact dimensions and rapid dynamic response are required. The motor supports precise rotary motion on axes that need repeatable starts, stops, and short positioning moves. Its compact housing also suits machine sections where available mounting space is limited.
The motor has a centering diameter of 95 mm that aligns the flange to machine frames, and standard dynamic balancing helps limit vibration during high-speed rotation. Power and feedback leads exit on the right side through a sealed industrial connector, which can simplify cable routing in tight cabinets. Continuous stall torque reaches 2.2 Nm, allowing the drive to hold a load at standstill, while a nominal speed of 4000 rpm supports short cycle times during motion. Position is reported by an integrated multi-turn absolute encoder, so the controller can retain location information across multiple revolutions after power is restored. The motor uses size 071 with length code A, has no shaft extension on side B, and relies on natural convection for cooling.
A blocking brake supplies 3.0 Nm of holding torque so vertical or suspended loads remain stationary when power is removed. Position data is transferred through digital servo feedback (DSF), which supports closed-loop accuracy at startup and during temperature changes. Torque is transmitted through a hardened shaft with a keyway, and contamination ingress is limited by a shaft seal. The motor has a single-ended shaft layout, which helps when rear clearance is limited and keeps the connection area accessible.
