Product Description:

The MDD090C-N-030-N2L-130PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into tightly regulated motion for positioning axes and gantry systems on automated lines. Integrated electrical, mechanical, and feedback components allow the drive to close velocity and position loops without external sensors. It is suited for closed-loop motion tasks that require accurate speed regulation and repeatable positioning across changing loads.

At standstill, the rotor can deliver a continuous torque of 10.4 Nm, allowing the drive to hold static loads without overheating. Once energized, it reaches a nominal speed of 3000 rpm, which supports high-resolution motion profiles. All power, brake, and encoder leads exit on Side A, and each interface uses a single plug-in connector to simplify wiring. The single-connector layout also helps keep cable routing organized where installation space is limited. Position data is returned through digital servo feedback (DSF), giving the controller shaft information immediately after power-up. A standard balancing grade is applied to the rotor, and the housing uses the finless enclosure common to the series.

For static holding, the integrated blocking brake supplies 11.0 Nm of holding torque, enabling vertical or indexing shafts to remain locked when supply power is removed. Mechanical alignment to adjoining gearboxes is simplified by the 130 mm centering diameter machined into the front flange. The output shaft has a keyway and a shaft seal that helps prevent lubricant washout and particle ingress. The shaft seal also helps protect the bearing area when the motor operates near dust or light splash. A standard shaft end is provided on the drive side only, which eliminates an extension on side B to save space. Length code C indicates the motor length used for this frame size.
