Product Description:

Bosch Rexroth Indramat manufactures the MDD090C-N-040-N2M-110GA2 synchronous motor within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it couples to Indramat servo amplifiers to provide closed-loop motion in assembly cells, packaging lines, and pick-and-place units. The design uses a 090 frame with length code C, delivering medium torque density while keeping the overall dimensions compact for tight machine layouts. This arrangement makes the motor suitable for servo axes that need repeatable position control and stable response during frequent start-and-stop cycles.

The stator produces a continuous torque of 10.4 Nm at standstill, allowing the axis to hold load without overheating during extended dwell periods. When energized, the rotor can reach a nominal speed of 4000 rpm, which is suitable for rapid indexing in medium-inertia equipment. Power and feedback conductors exit on side A, simplifying cable routing because the single connector remains accessible from the front of the cabinet. A 110 mm centering diameter aligns the flange to gearboxes or mounting plates. Position information comes from an integrated multiturn absolute encoder, so the controller can recover the shaft reference immediately after a power cycle without a homing routine.

For controlled stopping and power-off holding, a blocking brake supplies 11.0 Nm of static torque and is released electrically through the rear connector. Feedback is provided as digital servo feedback, matching the communication format expected by compatible drives. The rotor has a plain shaft that mates to couplings without keys, and a shaft seal helps prevent oil leakage and particulate ingress. Standard dynamic balancing minimizes vibration, the standard housing finish supports general-purpose environments, and the lack of a side-B shaft end simplifies integration when space behind the motor is limited.
