Product Description:

The MDD090C-N-030-N2L-130GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts commanded current into angular motion for automated axes that require precise velocity regulation. It is suited for positioning tasks on packaging, handling, and transfer equipment where stable speed control and repeatable response are required. The design follows the C length code within the 090 frame size, giving a consistent mechanical envelope for systems that use motors from the series. Standard housing and balancing practices simplify installation without requiring special vibration countermeasures.

Mechanical interfaces include a centering pilot of 130 mm that aligns the flange to the driven machine, and connections routed on side B, where a keyed connector handles both power and feedback cabling. This layout keeps the connection area organized and leaves the drive-side shaft end clear for the mechanical coupling. At standstill, the electromagnetic system can deliver a continuous torque of 10.4 Nm, keeping loads stable until motion resumes. During operation, the rotor reaches a rated speed of 3000 rpm, which works with drive-side commutation tables for sinusoidal current control. Standard housing material and the absence of a secondary shaft end reduce sealing surfaces, lowering potential ingress points in general-purpose factory environments.

Load holding during emergency stops is achieved through an integrated blocking brake that applies 6.5 Nm of static torque. Position information returns to the controller through Digital servo feedback (DSF), letting the motion loop close without external encoders. That feedback method allows the controller to monitor rotor position and motor speed during acceleration, steady motion, and stopping. The motor uses a plain shaft with a shaft seal, so lubricant stays contained while dust or coolant entry is limited. A standard shaft end on the drive side and no shaft extension at the opposite end simplify coupling choices for inline gearboxes or pulleys. Standard balancing helps keep residual vibration low during high-speed duty cycles.
