Product Description:

Bosch Rexroth Indramat manufactures the MDD071B-N-030-N2S-095GA2 in its MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated inverter current into precise rotary motion for positioning and speed control in automated assemblies. Its synchronous design allows the paired controller to regulate speed and position with repeatable response during start-stop cycles. The motor size 071, length code B, and standard housing keep its footprint small, while standard balancing helps limit vibration across the speed range. This helps maintain smooth axis behavior during frequent reversals. A blocking brake integrated at the non-drive end maintains shaft position when power is removed, which supports vertical or suspended loads.

During continuous stall conditions, the unit supplies 4.4 Nm of torque, so the servo can hold tooling or conveyors without exceeding its thermal capacity. Under commanded motion, it reaches a nominal shaft speed of 3000 rpm, giving adequate velocity for indexing, winding, or pick-and-place axes. The blocking brake develops 6.5 Nm of static torque to secure the shaft when the drive is disabled. A centering pilot of 95 mm simplifies concentric mounting to gearboxes or load couplings. Power and feedback leads exit on side A, and a keyed circular connector supports quick connection in modular machines. That arrangement also keeps cable routing predictable when the motor is mounted in tight machine frames. The shaft end is supplied in a standard single-ended configuration, which matches common couplers without additional machining.

In operation, the drive uses digital servo feedback (DSF) for closed-loop correction of position error at every cycle. This feedback arrangement supports stable commutation and accurate speed regulation as load conditions change. The rotor has a plain shaft with a fitted shaft seal, which helps limit lubricant migration at the drive end. A standard housing finish shields the stator laminations while leaving the centering face unobstructed. The compact motor layout also suits multi-axis gantries and other installations where mounting space is limited.
