Product Description:

The MDD071B-N-030-N2T-095PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it delivers rotary motion that can be tightly regulated by the connected drive, making it suited for positioning, contouring, or cyclic speed tasks in automated machinery and material-handling stations. Its frame code 071 and length code B give a compact footprint that integrates easily on mid-range axes where consistent torque and quick reversals are required.

At a continuous stall rating of 4.4 Nm, the rotor can hold or slowly move loads without thermal overload while the drive maintains closed-loop regulation. The motor reaches a nominal operating speed of 3000 rpm, aligning with controller output frequencies commonly used for packaging, printing, and assembly spindles. Mechanical centering is simplified by a 95 mm pilot diameter, allowing concentric alignment with gearboxes or mounts. Power and feedback conductors exit on side B, so cabinet wiring can remain parallel to the machine frame and avoid interference with moving parts. A splined shaft is not provided; instead, the unit uses a keyway interface that mates with standard keyed couplings for positive torque transmission.

Signal quality and position resolution are handled by an integrated multi-turn absolute encoder, so the axis reports its angle immediately after power-up with no homing sequence. The encoder works with digital servo feedback, enabling high-bandwidth current and velocity loops inside the Rexroth drive. For applications where dynamic braking is supplied externally, the motor is delivered without a holding brake, reducing mass and maintenance points. A factory-installed shaft seal guards the front bearing against splash and dust, permitting installation in IP-rated enclosures or directly on machinery with light exposure to coolant mist.
