Product Description:

The MDD071B-N-040-N2S-095PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded electrical input into tightly controlled mechanical rotation so that indexing tables, packaging axes, and assembly robots can maintain repeatable positioning under changing loads. Its synchronous design supports accurate acceleration and stable speed regulation during repeated start-stop cycles in automated equipment.

This model delivers a continuous standstill torque of 4.4 Nm, allowing the axis to hold static loads without overheating while still reserving headroom for dynamic peaks. During motion, its nominal speed of 4000 rpm matches drive stages that operate on higher fundamental frequencies, shortening cycle times in pick-and-place routines. Position and velocity signals are returned through digital servo feedback (DSF), enabling the controller to correct deviations in real time. Mechanical alignment with adjoining gearboxes and machine flanges is simplified by a centering diameter of 95 mm, and service wiring is straightforward because the power and encoder connectors are mounted on side A of the housing.

The motor is fitted with a blocking brake that produces 6.5 Nm of holding torque to keep vertical loads from drifting when power is removed. A factory-installed shaft seal helps prevent lubricant leakage and guards internal bearings from splash ingress, while the driven end carries a keyway so torque can be transmitted through standard keyed couplings. The unit has a motor size 071 frame with a compact motor length code B, which helps keep mass low without sacrificing thermal capacity. Standard balancing limits residual vibration, the single-ended shaft configuration omits a side B extension, and a molded connector interface supports quick exchange in modular machines. The cast aluminum housing remains standard across the series and provides a uniform mounting footprint for multi-axis installations.
