Product Description:

The MDD093B-F-020-N2L-110GA1 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated electrical energy into mechanical rotation for tooling, conveyor, and positioning axes across automated lines. The rotor is balanced to a standard grade to reduce vibration during continuous motion. A plain shaft with a standard end on side A supports straightforward coupling, while power and encoder conductors terminate on an integrated connector. The mechanical envelope follows motor length code B, which helps maintain a consistent footprint in existing machine layouts.

During continuous stall conditions, the motor supplies 14.5 Nm of torque, providing steady holding force without exceeding thermal limits. Under rated excitation, it reaches a nominal speed of 2000 rpm, aligning with drive profiles that favor high torque at moderate rotational speed. The stator jacket is prepared for liquid cooling, so heat from full-load operation can be carried away by external coolant instead of ambient air. This cooling method is useful in enclosed equipment where surrounding airflow is limited. Position and velocity data are returned through digital servo feedback (DSF), which supports closed-loop regulation with accurate speed and position information. Cabling exits on side A, and frame designation 093 matches standardized mounting flanges used in this motor family.

For holding and emergency-stop functions, the unit incorporates a blocking brake that generates 11 Nm of static torque when engaged. The brake supports load holding when drive power is removed, and it also assists with controlled stopping functions in the machine. Accurate concentric alignment with adjacent machinery is aided by a 110 mm centering diameter, which helps the motor seat correctly against mating surfaces. A shaft seal at the output journal helps protect the internal bearings from coolant splash and process debris. This arrangement is well suited to equipment where the drive end may be exposed to contamination during normal operation.
