Product Description:

Bosch Rexroth Indramat builds the MDD090C-N-040-N2M-110GR0, a synchronous servo motor in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts the regulated output of a compatible Indramat drive into precise rotary motion for indexing tables, gantry axes, and material transfer stages on automated lines. Its standard housing and rotor balancing allow direct installation in machinery without additional damping elements. This layout supports compact axis assemblies where repeatable motion and fast response are required.

At standstill, it can deliver 10.4 Nm of continuous torque, giving stable holding force for positioning axes. During rated operation, the rotor reaches 4000 rpm, supporting short cycle times in packaging or pick-and-place cells. A 110 mm centering diameter aligns the stator flange with precision mounting faces, and the terminals exit on the right side through a sealed connector that suits typical plant cable routing. Length code C identifies the medium magnetic stack within the frame, and size code 090 indicates the motor diameter used for this housing. Standard dynamic balancing keeps vibration levels low, while the housing releases heat to ambient air. Power and feedback share a single connector, which helps keep cable routing compact, and position data is transferred as digital servo feedback to the controller.

The mechanical interface uses a plain shaft that mates with clamp or collet couplings, and a shaft seal helps keep coolant or dust from migrating along the journal into the bearing cavity. Because the unit is supplied without a blocking brake, the drive must furnish holding torque or an external lock when power is removed. An integrated multi-turn absolute encoder returns absolute position over several revolutions, so the axis can resume service immediately after startup or an emergency stop. This feedback arrangement also lets the control system retain position information without a homing cycle after every restart.
