Product Description:

The MDD090A-N-020-N2L-110GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled electrical input into rotational motion for positioning or speed-regulated axes in automated machinery. The model occupies the 090 frame class and uses an A-length housing, giving machine builders a compact actuator that fits standardized mounting patterns while maintaining the centering diameter used by the series.

In static conditions, the motor delivers a continuous torque of 3.7 Nm, allowing it to hold loads without overheating when the shaft is locked. Under rated supply from the drive, the rotor can reach a nominal speed of 2000 rpm, which is the normal operating speed for this motor winding. For emergency or power-off restraint, the integrated blocking brake applies 6.5 Nm to the shaft, helping prevent drift on vertical or suspended axes. The mechanical interface uses a centering pilot of 110 mm, which aligns the housing to the mating flange, and a plain shaft that supports coupling with a suitable hub.

Electrical and feedback leads exit on Side B of the stator through a connector, which keeps cable routing straightforward in machine installations. Position data are transmitted by the integrated digital servo feedback (DSF) device, enabling closed-loop control without an external encoder. Standard dynamic balancing helps reduce vibration through the normal speed range, and the sealed housing includes a shaft seal to help block coolant or dust ingress. The 090 frame code gives the motor a compact overall package while retaining the standard housing style and a single shaft end. This layout is suitable for gantries, indexing tables, and other motion modules that rely on precise servo regulation.
