Product Description:
The MDD071C-N-030-N2T-095GA1 is a motor for digital drive controllers built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a permanent-magnet synchronous unit, it converts command currents from a servo amplifier into controlled mechanical rotation for positioning tasks, indexing tables, and general motion sequences on automated machinery. The C length code and 071 frame size place it in the medium power range, while standard housing and balancing keep installation straightforward inside electrical enclosures. Its permanent-magnet rotor helps the drive produce responsive torque changes during rapid starts, stops, and reversals.
Its continuous torque at standstill reaches 6.6 Nm, allowing the axis to hold loads without overheating when the rotor is locked. Under rated excitation, the rotor spins at a nominal speed of 3000 rpm, a common value for servo loops that need quick response yet moderate gearbox ratios. The front-face centering diameter of 95 mm aligns the flange to machine frames and ensures concentricity. Power and feedback cables exit on side A through a keyed connector, simplifying cable routing in compact cabinets. Position data is generated by the integrated multi-turn absolute encoder, so the controller always knows shaft position even after power loss. Standard housing and plain balancing minimize vibration and simplify alignment during these duty cycles.
The blocking brake integrated on the non-drive side applies 3.0 Nm of torque to hold the axis when supply power is removed, preventing drift on vertical loads. Feedback to the drive is transferred through Digital servo feedback (DSF), giving high-resolution incremental and absolute data for speed and current loops. Mechanical output is delivered through a plain shaft with a standard single-ended design, so couplings or pulleys mount directly without secondary machining. The standard shaft seal keeps lubricants inside and contaminants out under routine washdown or coolant mist environments. This arrangement supports repeatable positioning when the axis must return to stored coordinates after an interruption.
