Product Description:

The MDD071B-N-040-N2S-095GB1 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated current into precise rotary motion for automated packaging lines, machining centers, and material-handling axes. Its electromagnetic design supports quick acceleration, stable velocity control, and repeatable positioning in multi-axis industrial systems under closed-loop feedback from the connected drive. This operating profile makes the motor suitable for applications that require accurate starts, stops, and speed changes during repetitive production cycles.

At standstill, the rotor can sustain a continuous torque of 4.4 Nm, supplying holding force without overheating during idle clamping or low-speed feed. The winding arrangement allows a nominal shaft speed of 4000 rpm, so high-cycle machinery can run at production pace while maintaining synchronization with the inverter. A built-in mechanical brake delivers 3.0 Nm of static torque, and the blocking brake helps prevent vertical loads from drifting when power is removed. Mounting accuracy is aided by a 95 mm centering diameter that aligns the flange concentrically with adjacent components. The housing is intended for typical industrial environments where dependable alignment and controlled thermal behavior are important for consistent motion.

All power and encoder lines exit on Side B, and a sealed screw-lock connector supports secure cable attachment. The output end uses a plain shaft, and a shaft seal around the journal helps protect the primary bearing from fluid ingress. Because the shaft end follows the standard profile without a rear extension, couplings or pulleys can seat at the proper depth without interfering with nearby machine parts. Motor size 071 and length code B set the body dimensions for this frame. Position and temperature are reported through Digital servo feedback (DSF) for closed-loop control, allowing the connected drive to monitor operating conditions while maintaining accurate command response.
