Product Description:

The MDD071B-N-040-N2T-095PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers in automated machinery, where it converts commanded current into precise rotary motion for coordinated speed and position control. Integrated position feedback allows the axis to follow programmed trajectories in pick-and-place stations, packaging equipment, and light machining centers. Because the feedback device is built into the motor, the drive receives position data directly from the axis without requiring a separate external sensor.

The motor delivers a continuous standstill torque of 4.4 Nm, allowing stable holding under rated current without thermal overload. Its nominal speed reaches 4000 rpm, giving the shaft a high continuous operating speed for dynamic axis motion. For electrical interfacing, power and feedback lines exit on the right side through a single industrial connector, which helps keep cable routing compact. Position data comes from an integrated multi-turn absolute encoder, so the drive controller can track multiple revolutions without battery backup. Real-time angle information is transmitted through digital servo feedback for fast control-loop updates.

The blocking brake supplies 3.0 Nm of static torque to secure the axis when power is removed. During installation, the housing seats in a spigot with a centering diameter of 95 mm, which helps align the motor with the machine interface. A keyway shaft transfers torque to couplings, while a shaft seal helps limit lubricant migration and dust entry at the output end. Frame size 071 and length code B give the motor a moderate footprint for light to medium-duty servo axes. The rotor is dynamically balanced for smooth running across the speed range, and the shaft is supplied without a side-B extension to keep the overall length shorter.
