Product Description:

The MDD090A-N-040-N2M-110GA1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. In industrial automation, the unit couples to digital drive controllers to convert commanded current into accurate rotary motion on indexing tables, pick-and-place axes, and light machining spindles. Its sealed construction, integrated position sensing, and standardized flange pattern allow straightforward installation while maintaining repeatable speed and torque delivery during continuous or cyclic duty cycles. The motor is suitable for compact machine axes that require precise starts, stops, and stable speed regulation during normal operation.

The motor has a nominal shaft speed of 4000 rpm, which gives the controller a clear upper operating speed for synchronous motion profiles. When the rotor is locked, it can supply a continuous torque of 3.7 Nm, allowing low-speed holding and creep moves without excessive heat buildup. Power and feedback conductors exit on side A through a single keyed connector, which helps keep wiring compact and reduces the chance of mismatched connections. The centering flange is machined to 110 mm, supporting accurate alignment with mounting faces and helping limit radial runout at the coupling point.

For position tracking, the motor includes an integrated multi-turn absolute encoder that sends digital servo feedback (DSF) to the controller, removing the need for an external resolver and supporting immediate position availability after power-up. A blocking brake rated at 6.5 Nm holds the shaft when power is removed, which is useful on vertical axes and during controlled stops. The output end uses a plain shaft with a factory-installed shaft seal to help keep dust away from internal components and reduce lubricant escape. Standard balancing keeps vibration low for the 090 frame with length code A, and the universal housing style matches the mounting pattern used across nearby models in the series.
