Product Description:

The MDD071B-N-040-N2T-095GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for mounting on digital drive controllers, the unit converts electrical commands into controlled rotary motion for automated machinery. By pairing its internal position sensor with the drive, the motor delivers closed-loop accuracy for packaging, material handling, and general factory automation axes.

At the core of its performance range is a continuous standstill torque of 4.4 Nm, allowing the shaft to hold load without overheating during static positioning cycles. When motion is required, the rotor reaches a nominal speed of 4000 rpm so the axis can execute rapid indexing routines. A blocking brake rated at 6.5 Nm secures the shaft when power is removed, supporting vertical or suspended loads. Position data are supplied by an integrated multiturn absolute encoder, while velocity and phase information are returned through Digital Servo Feedback (DSF) to the connected drive, eliminating the need for external sensors. These electrical features work with the standard housing and internal balancing to keep vibration and thermal rise within normal operating limits.

The flange uses a 95 mm centering diameter that mates to gearboxes or machine frames without additional sleeves. Power and feedback conductors exit through a right-side connection, implemented with a sealed connector to simplify cabinet routing. A plain shaft in the standard single-ended configuration transmits torque, and a shaft seal protects the bearing set from coolant or dust ingress. The rotor uses size code 071 and length code B, and it is balanced to the standard class for smooth rotation. Standard housing construction and the absence of a side-B shaft end allow compact installation in multi-axis assemblies.
