Product Description:

The MDD090B-N-020-N2L-110GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat and positioned within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into repeatable torque and speed, enabling precise motion in automated assembly cells, gantry axes, and processing machines. The model carries a standard housing and rotor balancing so it can be mounted directly into machinery without supplemental vibration isolation, supporting dependable duty cycles in industrial environments. It is suitable for applications that rely on consistent response during repeated indexing, feed, and transfer movements across long production runs.

At standstill, the motor can deliver a continuous torque of 7.2 Nm, giving the drive enough margin for positioning tasks that require static load support without overheating. During rotation, its electromagnetic design permits a nominal speed of 2000 rpm, a value matched to drive controllers that supply the corresponding fundamental frequency. Rotor position is returned through digital servo feedback (DSF), allowing the control loop to resolve multi-turn position data with high granularity. Mechanical centering is handled by a 110 mm pilot diameter that aligns the flange to adjacent machine frames. All power, feedback, and brake conductors exit on side A, which simplifies cable routing in cabinets laid out for front-facing service access. That cable direction is also useful where space around the opposite side of the motor is limited.

A blocking brake is integrated and can restrain loads with up to 6.5 Nm of static torque when power is removed, making vertical or load-holding axes easier to secure. The motor size code 090 with length code B uses a magnetic stack that pairs with drives in the 6 A to 15 A range. Power and sensor lines terminate on a molded connector, which keeps the electrical interface compact at the motor body. Motion is transmitted by a plain shaft that is protected by a shaft seal and supplied only on the drive end, avoiding overhung mass on side B. This layout helps keep the rear profile simpler for guarding and nearby machine components.
