Product Description:

The MDD090B-N-030-N2L-110GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it is used on articulated arms, gantries, and other precision axes to deliver commanded torque and speed under closed-loop control. The unit converts three-phase electrical power into regulated mechanical rotation, allowing industrial automation equipment to position loads quickly and repeatably while maintaining feedback integrity through its integrated encoder system. Typical applications include packaging lines, pick-and-place systems, and other machinery that requires accurate axis movement during repeated operating cycles.

At standstill, the motor delivers 7.2 Nm of continuous torque, so static loads can be supported without overheating under rated conditions. During motion, it reaches 3000 rpm, matching controllers that require moderate-speed positioning across a wide range of automated tasks. The centering shoulder measures 110 mm, giving the flange a precise locating surface for concentric alignment. Power and feedback plugs exit on the right side, which can simplify cable routing in tightly arranged machine layouts. A removable connector interface allows the harness to be disconnected without disturbing the motor housing. Standard dynamic balancing helps reduce residual vibration, the standard housing releases heat through natural convection, and the shaft seal helps block dust and oil from entering sensitive internal areas.

For holding functions, an integral brake supplies 6.5 Nm of static torque, so vertical loads can remain fixed when power is removed. Position data is reported through digital servo feedback (DSF), allowing accurate commutation and stable speed regulation during changing load conditions. The rotor stack uses length code B, pairing with the 090 frame to provide a balanced relationship between inertia and torque output. A plain shaft accepts couplings or pulleys, and the design omits a side-B shaft end to keep the overall motor length compact. The motor also uses a shaft seal, standard balancing, and a standard housing, which supports consistent installation across compatible MDD motor applications.
