Product Description:

The MDD071B-N-030-N2T-095PB2 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies precisely metered rotary power to automation axes that require tight position and speed control. The unit uses frame size 071 with length B, providing a compact footprint for conveyor stations, pick-and-place heads, and auxiliary machine-tool functions. Its standard housing, standard balancing, and single-ended shaft support straightforward mechanical installation in multiple mounting orientations.

At standstill, the motor can produce 4.4 Nm of continuous torque, allowing fixtures or loads to be held without drift. Under rated electrical excitation, the rotor reaches a nominal speed of 3000 rpm, covering most medium-speed positioning requirements without gear reduction. In power-off or emergency states, an internal brake delivers up to 6.5 Nm of holding torque to help prevent uncommanded motion on vertical or suspended axes. Accurate mechanical alignment is aided by a flange centering diameter of 95 mm, which provides a repeatable reference for coupling to gearboxes or mounting plates. Real-time position data are returned through digital servo feedback, enabling high-bandwidth current and velocity loops in the associated drive.

Service wiring exits toward the rear because the connectors are located on Side B of the stator, helping keep cables clear of the load side. Output torque is transmitted through a shaft with a keyway, simplifying rigid attachment to pulleys, pinions, or couplings. An integrated multi-turn absolute encoder records angular location over multiple revolutions, eliminating the need for a homing cycle after power is restored. A front-end shaft seal helps block lubricant egress and airborne contaminants, supporting reliable operation in enclosed machining or material-handling cells while protecting the bearing set.
