Product Description:

The MDD071B-N-030-N2T-095PA0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for installation on medium-power axes, it combines permanent-magnet excitation with electronic commutation to deliver responsive torque across a broad speed range. Its role in industrial automation is to provide closed-loop rotary motion for digital drive controllers used in assembly, packaging, material-handling, and similar automated machines.

At a standstill, the motor delivers a continuous torque of 4.4 Nm, allowing holding tasks without overheating. When driven to its nominal speed of 3000 rpm, the motor provides balanced power for mid-frame axes. A centering diameter of 95 mm aligns the flange with gearboxes or machine plates. Power and feedback cables exit on side A, so panel layouts can be arranged around that orientation. The shaft is machined with a keyway, giving positive mechanical locking to pulleys or couplings and helping prevent slippage during repeated start-stop cycles. Standard rotor balancing minimizes vibration at speed, and the B length code keeps the overall stack size moderate for the 071 frame. A molded connector completes the electrical interface and simplifies cable connection.

Feedback precision is supplied through digital servo feedback paired with an integrated multi-turn absolute encoder, enabling the controller to read true position after power-up without homing moves. The motor ships without a holding brake, so external clamping or drive-generated torque must maintain position during power loss. To protect internal bearings, the shaft end is fitted with a shaft seal, which helps keep out airborne coolant and dust. The motor uses the series connector arrangement, and the lack of a second shaft end leaves the drive end dedicated to the coupling.
