Product Description:

The MDD090C-N-040-N2M-130GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor matched to digital drive controllers, it delivers closed-loop torque for positioning and velocity control tasks in automated machinery and assembly cells. Its mechanical format follows the 090 frame class, allowing it to fit mounting patterns used within the series.

The motor’s centering pilot measures 130 mm, establishing the reference diameter that aligns the housing to gearbox flanges or machine frames. A continuous standstill torque of 10.4 Nm indicates the sustained load the stator can produce while locked, so external brakes or couplings can be selected to match the axis demand. When energized at rated frequency, the rotor reaches 4000 rpm, giving fast traverse speeds without gearbox overdrive. Power and feedback leads exit on the right side, an arrangement that simplifies routing in cabinets where multiple axes are stacked. The motor uses a connector interface for the cable connection. Standard dynamic balancing keeps vibration within ISO limits, and the C-length code indicates the longest rotor and stator stack offered for the 090 frame, maximizing torque density inside the standard housing.

Axis feedback is delivered by an integrated multi-turn absolute encoder that reports position over multiple revolutions without battery support, while the drive reads this data through Digital servo feedback (DSF) signals for high-resolution control loops. The front bearing carrier includes with a shaft seal to reduce lubricant migration into the stator air gap. Motion is transferred through a plain steel shaft, and the absence of keyways minimizes stress concentrations. The shaft end is supplied only on side A to conserve length. Emergency holding is handled externally because the motor is supplied without a blocking brake, allowing the application to use mechanical clamps or dynamic drive torque as needed.
