Product Description:

The MDD090C-N-020-N2M-110GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct connection to digital drive controllers, it converts regulated current from the inverter into accurately metered torque and speed. The unit is used on machine axes that demand repeatable positioning, coordinated interpolation, and fast reversal, making it suitable for machining centers, handling gantries, and assembly stations where closed-loop motion is critical. This operating role supports synchronized motion in automated equipment that requires consistent response during acceleration and reversal.

During static load conditions, the motor delivers a continuous torque of 10.4 Nm, allowing it to hold tooling or fixtures without additional gearing. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm, which is well matched to moderate-speed spindle or conveyor duties. Accurate flange alignment is supported by a centering diameter of 110 mm, which mates with standardized mounting bores. All electrical interfaces are on side A, so cable routing remains consistent across multi-axis installations. Rotor position data comes from an integrated multi-turn absolute encoder, giving the controller absolute angle information over many revolutions. For power-off holding, a blocking brake rated at 6.5 Nm clamps the shaft to help prevent uncommanded motion on vertical or suspended loads.

Feedback signals return through digital servo feedback, reducing analog drift and letting the drive close current and velocity loops with high gain. The power leads lock into a keyed connector, which supports quick cable changes while preserving the standard housing layout. Mechanical output is delivered by a plain shaft with a shaft seal, which helps limit the ingress of cutting fluids or dust. Standard dynamic balancing keeps residual vibration low, and the motor's length code C maintains a compact envelope within the size 090 frame. Because no shaft projects from the rear, the housing can be mounted flush against panels or bearing supports in space-constrained equipment.
