Product Description:

The MDD071A-N-040-N2S-095PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies precise velocity and position regulation in automated handling stations, small conveyor sections, and packaging lines. The unit is built in frame size 071 with motor length code A, and its standard aluminum housing contains an integrated blocking brake that holds the load when control power is absent. This layout supports repeatable motion during operation and secure holding when the axis is stopped.

During normal operation, the rotor reaches a nominal speed of 4000 rpm, while continuous torque available at standstill is 2.2 Nm. When power is interrupted, the mechanical holding brake applies up to 3.0 Nm of static torque to prevent back-driving. Feedback is provided through Digital servo feedback (DSF), enabling the drive to calculate position without additional sensors. Power, brake, and feedback conductors are routed through a connector on side B of the stator housing, which helps simplify cable runs where right-hand service space is preferred. The standard housing surface conducts heat directly to ambient air, so no external blower is required.

Mechanical interface features include a centering pilot of 95 mm that aligns the flange to gearboxes or machine plates with minimal radial error. The output shaft uses a keyway to transmit torque through keyed couplings, and the rotor uses standard balancing for smooth rotation across the full speed range. A contact lip on the front bearing provides sealing, identified as with a shaft seal, to help limit grease migration and dust ingress. The shaft follows a standard single-ended arrangement with no second shaft on side B, which helps preserve the motor's compact depth while maintaining compatibility with inline couplings.
