Product Description:

The MDD090C-N-020-N2M-110GL1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. This synchronous unit is supplied for integration with digital drive controllers, where it converts electrical power into precisely regulated rotary motion for positioning axes and continuous-duty spindles used in industrial automation equipment. The shaft terminates on side A only, following the standard configuration that omits a side B extension.

The motor delivers a continuous standstill torque of 10.4 Nm, allowing it to hold or start loads without overheating when airflow is limited. Its nominal operating speed of 2000 rpm sets the reference operating speed for rated production cycles. A centering flange measuring 110 mm simplifies alignment to gearboxes or machine frames, and standard dynamic balancing keeps vibration within the limits for this frame size. Cabling is routed on the left side through a sealed connector, which helps reduce installation space in tight cabinets. Size code 090 combined with length code C indicates the active iron length and overall housing dimensions, while the standard housing finish matches adjacent MDD models.

An integrated multi-turn absolute encoder provides position data, and the drive interprets it through Digital servo feedback (DSF) for closed-loop accuracy across the full speed range. Motion can be locked mechanically when power is removed because a blocking brake rated at 6.5 Nm clamps the rotor, and the brake is energized by the controller and releases automatically on command. The output uses a plain shaft for direct coupling, and the rotor passage is built with a shaft seal to limit contamination. Standard housing and connector orientation support smooth rotation during normal operating duty.
