Product Description:

The MDD090C-N-030-N2M-110GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotary motion and position feedback to automated axes that require precise speed regulation. Its standard housing, plain shaft geometry, and integral blocking brake allow the unit to fit directly into machine frames where reliable holding and fast dynamic response are required.

This model delivers a continuous stall torque of 10.4 Nm, giving the drive enough reserve to hold or accelerate loads without overheating when the rotor is locked. Under rated electrical frequency, it reaches a nominal speed of 3000 rpm, enabling integration into feed systems that operate in the medium-speed range. When power is removed, the mechanical holding brake supplies 6.5 Nm of static torque to prevent shaft rotation. Accurate concentric alignment during installation is maintained by a centering diameter of 110 mm. Power and feedback conductors exit on Side B through a single industrial connector, which simplifies cable routing in compact control cabinets.

Position data is transmitted through Digital servo feedback (DSF) that works with an integrated multi-turn absolute encoder, so the drive always knows shaft position after power-up. The motor has length code C and frame size 090, a combination that balances inertia and torque density for mid-range loads. A fitted shaft seal blocks oil and dust at the bearing journal, and the rotor is balanced to standard quality to minimize vibration. The motor has a plain shaft, and the shaft end remains standard on the drive side only, with no secondary extension on side B. Electrical termination relies on a connector interface that matches common Bosch Rexroth drive cables.
