Product Description:

The MDD071B-N-030-N2M-095GA0 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It interfaces directly with digital drive controllers to convert commanded current into controlled motion for industrial automation. Its frame size 071 and B length code place the unit in a medium-torque class suited to compact assemblies that still require high dynamic response. By combining encoder functions, power connection, and sealed mechanics in one housing, the motor supports packaging lines, machine tools, and material-handling equipment.

Electrical and mechanical parameters show how the axis is intended to operate. At stall, the rotor can deliver 4.4 Nm of continuous torque, with heat carried through the standard aluminum housing. Under rated excitation, the shaft reaches 3000 rpm, so the servo drive can generate rapid moves without gearbox multiplication. Motor phasing and power are supplied through a connector mounted on side A, which keeps cable routing on the machine's drive side. Position data returns over digital servo feedback (DSF), allowing the controller to close loops with microsecond-level resolution.

The centering pilot measures 95 mm, which helps the motor seat precisely against gearheads or adapter plates without radial misalignment. Feedback comes from an integrated multi-turn absolute encoder, so the axis position remains available after power loss. The design is supplied without a blocking brake, so vertical axes require an external holding device. A plain shaft with a factory-installed shaft seal helps keep lubricant in place and limits moisture entry into the interior. There is no secondary shaft extension on side B, which simplifies coupler alignment where installation space is limited. Moderate mass also keeps rotor inertia compatible with common belt or ball-screw loads, and the exterior coating helps protect the housing in typical industrial settings.
