Product Description:

The MDD090B-N-020-N2L-130GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and part of the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies regulated rotary motion for positioning tables, packaging axes, and other industrial automation loads that require precise velocity and torque control. Its mechanical layout follows the standard housing and balancing rules used in the series, which keeps installation dimensions consistent across comparable frame lengths. This arrangement helps maintain stable running behavior during continuous-duty operation.

The motor sustains a continuous stall torque of 7.2 Nm, allowing the driven axis to hold static loads without thermal overload, and it reaches a nominal operating speed of 2000 rpm under rated drive power. A centering recess of 130 mm simplifies accurate alignment on machine frames, and the power and feedback connectors are located on the left side so wiring can exit in the same direction as adjacent modules. These connections use a sealed connector interface for secure cable attachment. Standard dynamic balancing limits runout forces, while the absence of a blocking brake reduces axial length for applications where holding torque is supplied by the drive. The B-length code increases stack height compared with the A length, which raises torque density without changing the mounting pilot.

Position data is returned through digital servo feedback, enabling high-resolution commutation and diagnostic functions inside the controller. Output torque is transmitted by a plain shaft that omits keyways to reduce stress concentrations, and a dedicated shaft seal protects the internal bearings from coolant splash or lubricant migration. The frame code 090 indicates the overall flange size. The motor has a single shaft end on side A, which supports straightforward coupling to inline gearboxes.
