Product Description:

The MDD071A-N-040-N2S-095PR0 is a synchronous servo motor from the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified as a motor for digital drive controllers, it is intended for closed-loop positioning and velocity tasks in industrial automation. The unit has motor size 071 with the compact A length code, which gives it a short axial footprint while keeping the diameter used by this motor family. In automated systems, this layout supports responsive motion on feed axes, transfer units, and other mechanisms that require repeatable control under changing loads.

This model delivers a continuous standstill torque of 2.2 Nm, enabling stable force production during static holding or slow-speed moves. Its operating range reaches a nominal speed of 4000 rpm, allowing fast indexing when paired with a compatible inverter. Rotor alignment uses standard balancing, which helps limit vibration during high-speed cycles. The flange has a centering diameter of 95 mm for repeatable seating against gearboxes or machine frames. Connections exit on the right side through a sealed industrial connector, which helps keep cable routing clear of nearby machine elements. A fitted shaft seal protects the internal bearings from coolant splash, and the housing remains in a standard form for straightforward installation.

Feedback is supplied through digital servo feedback, giving the controller position data and commutation signals for closed-loop operation. Because the unit is supplied without a blocking brake, holding force during power-off conditions must be provided externally when the axis must remain fixed. The single-ended rotor uses a standard shaft end without a side B extension, and torque is transmitted through a keyway for positive mechanical coupling. The keyed shaft and the connector-based electrical interface support clean integration into automated equipment where controlled speed, position, and holding behavior must be managed by the drive system.
