Product Description:

The MDD090A-N-040-N2M-110GR0 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 converts electrical power from the drive into rotary motion for positioning or speed-regulated axes in automated machinery. The unit integrates with Indramat drive systems to support closed-loop control where consistent torque and rapid acceleration are required in assembly lines, packaging cells, and material-handling stations.

For the mechanical interface, the motor uses a centering diameter of 110 mm, allowing precise seat alignment against gearboxes or flanges. The power and feedback conductors exit on the right side through a sealed connector, which helps keep cable routing compact and orderly. Balancing is standard, so residual vibration levels are suitable for direct coupling to light-duty loads. At standstill, the motor can deliver 3.7 Nm of continuous torque, giving adequate holding force for small pick-and-place axes. Position data is generated by an integrated multi-turn absolute encoder, so multiple mechanical revolutions are tracked internally after power interruptions. The housing is standard, with no additional surface-cooling fins or liquid channels.

Dynamic motion is supported up to 4000 rpm. Feedback is handled through Digital servo feedback (DSF), which supports closed-loop operation in matching drive systems. The design follows motor size 090 and length code A, so the active stack fits a compact footprint in tight machine frames. The motor has a plain shaft with a shaft seal, which helps limit lubricant egress when the shaft passes through oil-filled gearheads. Because the shaft end is standard and not extended on side B, installation depth is minimized. The motor is supplied without a blocking brake, so static holding torque must be provided by the drive or external clamps.
