Product Description:

The MDD090B-N-040-N2L-110GA1 servo motor comes from Bosch Rexroth Indramat’s tough MDD Series, a range built for jobs that expect exact positioning and fast shifts. With a rated speed at 4000 rpm, this one keeps machines moving quick when the work needs it most. The motor size brings a 090 mm frame, which means a sturdier setup—not likely to wobble or bend under lots of cycles. Power lines up for high-usage spots, and a 110 mm centering diameter helps fit into most setups without weird gaps or bracket tricks.

Inside, a natural convection cooling system moves heat out during regular cycles, letting this model work in crowded machines or cabinets that stay limited on extra air or fans. There’s IP65 protection, keeping both dust and lower-pressure wash water out of the places that typically matter most. An integrated multiturn absolute encoder manages feedback here, responding to shifts so controls know exact shaft placement at nearly all points. This exact feedback makes tight process control easier, cutting down drift or surprise jerks. The double keyway shaft uses a standard DIN format and stands ready for backlash-sensitive work.

Electrics run to a plain, rotatable connector with blocked pins to keep everything locked in, and the sturdy winding insulates against daily heat and short, sharp rises from restarts or heavy torque. A black coat fights off scratches and regular indirect bumps out on the floor. Position sensors and the encoder link into drives running Rexroth or general-purpose software. For manufacturing jobs like robotics arms, automated shuttles, or flexible conveyor modules, slotting in the MDD090B-N-040-N2L-110GA1 means use that avoids fiddly adjustments and regular downtime. This size fits easiest when steady tracking and repeat starts really matter, and automation that likes to stay tight on landings will get what’s needed.
