Product Description:

The MDD071B-N-040-N2S-095GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for installation on digital drive controllers where precise torque and speed regulation are required for industrial automation tasks such as indexing tables, material-handling axes, or compact machining spindles. By combining permanent-magnet excitation with electronic commutation, the motor supplies continuous rotary motion that can be tightly coordinated with external feedback devices and motion profiles.

The motor’s centering pilot measures 95 mm, providing a defined locating surface that keeps the stator concentric with connected gearboxes or mounting flanges. A continuous standstill output of 4.4 Nm allows it to hold static loads without overheating, while a nominal operating speed of 4000 min⁻¹ supports fast cycle times in pick-and-place or spindle duties. Power and feedback conductors exit on Side B, a layout that simplifies wiring inside tight cabinets. Position data are transmitted through digital servo feedback, enabling high-resolution closed-loop control. For power-off safety and quick axis locking, the integrated brake delivers a holding torque of 6.5 Nm; this mechanical restraint eliminates drift when drives are disabled.

A plain shaft is supplied so couplings or pulleys can be press-fitted without keyways, reducing run-out in servo loops. There is also a shaft seal, which blocks coolant splash or dust from entering the front bearing during wash-down or machining operations. With the frame classified as size 071 and a “B” length code, the motor occupies minimal space yet provides enough thermal mass for continuous duty. These mechanical provisions complement the electrical ratings discussed above, resulting in a unit that integrates easily into multipurpose automation modules while maintaining predictable dynamic behavior.
