MDD071B-N-040-N2T-095PL2
The MDD071B-N-040-N2T-095PL2 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 electrical commands from an inverter into precise mechanical rotation needed in automated packaging lines, material-handling axes, and coordinated multi-axis machining cells. By combining permanent-magnet excitation with closed-loop feedback, the unit supplies repeatable torque and speed so individual stations can maintain cycle accuracy across long duty periods. This operating profile suits machinery that depends on steady acceleration, accurate stopping, and consistent positioning during repeated cycles.
The motor uses a centering diameter of 95 mm, which aligns the flange concentrically to help limit runout on coupled shafts. At standstill, the rotor can deliver 4.4 Nm of continuous torque, giving the axis stable low-speed holding capability for indexing tasks. When energized at rated voltage and frequency, the shaft can reach a nominal speed of 4000 rpm, matching servo applications that require both responsive travel and controlled motion. Axis safety is supported by an integrated blocking brake that develops 6.5 Nm of static torque to hold the load during power loss. Position data is generated by an integrated multi-turn absolute encoder, allowing the drive to track multiple revolutions without battery support. This combination supports smooth motion in transfer, feed, and positioning duties.
Electrical terminations are placed on the left side of the frame and use a keyed connector, which can simplify cable routing when the drive is mounted beside or below the axis. Feedback to the controller is transferred through digital servo feedback (DSF) signals, supporting real-time velocity and position correction during operation. A shaft seal is fitted to help protect the internal bearings from fine dust or fluid spray. The motor uses a keyway shaft with a standard single-ended output, which allows straightforward coupling to common transmission elements. Its size 071 housing with length code B provides a compact installation footprint without adding a second shaft extension on side B.
