MDD071B-N-040-N2S-095PL0
The MDD071B-N-040-N2S-095PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts the three-phase output of a compatible inverter into regulated mechanical rotation. In factory automation, this unit drives indexing tables, pick-and-place heads, and light machining spindles where rapid response and repeatable positioning are required. Its electrical interface and feedback format allow direct connection to compatible Rexroth controller families for straightforward integration on new or retrofit motion axes. When paired with a suitable drive, the motor supports accurate speed control and repeatable axis positioning during cyclic machine operation.
At stall, the motor delivers 4.4 Nm of continuous torque, and under rated bus voltage the rotor can reach a nominal speed of 4000 rpm. Accurate concentric mounting is assisted by a 95 mm centering diameter machined into the flange. Power, encoder, and brake conductors exit through a left-side connection that uses a molded connector, helping keep wiring clear of adjacent hardware in compact installations. Closed-loop regulation relies on digital servo feedback, which provides high-resolution position data to the drive for stable motion control. The design belongs to frame 071, carries a standard dynamic balancing grade, follows motor length code B, and is supplied with a single-ended shaft that omits a side-B extension.
The mechanical interface uses a keyed shaft, and it includes a shaft seal to limit the ingress of coolants or dust at the front bearing. Because the unit ships without a blocking brake, any static holding force must be furnished by the drive system or by external clamps. The enclosure uses a standard housing, matching the usual thermal and protection arrangement of the series while keeping the motor compact. The keyed shaft provides a positive connection to couplings or transmission elements, and the front seal helps protect the bearing area during regular machine operation. This version is suited to axes that rely on controlled drive torque for holding rather than an integrated brake mechanism.
