Product Description:

The MDD090B-N-020-N2L-130GB1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor built for digital drive controllers where precise closed-loop torque and speed regulation are required in automated machinery. By combining an internally mounted position sensor with a built-in blocking brake, the unit provides controlled rotary motion and secure holding capability for axes in packaging lines, gantry systems, and material-handling stations.

Within this B-length, size-090 frame, the motor delivers a continuous standstill torque of 7.2 Nm, allowing it to maintain load without overheating during permanent stall conditions. During operation, it can reach a nominal mechanical speed of 2000 rpm, which is the synchronous operating speed used with the matched drive. Accurate mechanical alignment is supported by a centering diameter of 130 mm. Power and feedback cables exit on side B through a prewired connector interface that simplifies cable routing. When power is removed, the blocking brake provides a holding torque of 6.5 Nm, helping prevent uncommanded shaft movement on suspended or vertical loads.

A shaft seal is fitted to help keep grease in and contaminants away from the bearing set. Rotor balance follows the Standard grade to reduce vibration across the speed range. Position and velocity signals are transmitted through digital servo feedback (DSF), allowing high-resolution control loops in the drive. The output side uses a plain shaft, and the motor has no second shaft end on side B. A standard housing and normal shaft end give the motor a straightforward mechanical layout for coupling to the driven machine.
