Product Description:

The MDD090A-N-030-N2L-130GR0 synchronous servo motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers closed-loop rotary actuation for automated machine axes. Its frame size 090 and motor length code A give it a moderate footprint that fits packaging stations, pick-and-place modules, and material-handling gantries where continuous positioning accuracy is required. In automated equipment, this arrangement allows the drive system to command precise starts, stops, and speed changes during repeated motion cycles.

During sustained stall operation the rotor supplies 3.7 Nm of torque, which supports steady-load holding and low-speed axis control within the motor's continuous operating range. The shaft can be driven up to 3000 rpm, matching common servo inverter speed ranges in indexing, transfer, and feed applications. Accurate mechanical seating is achieved with a centering diameter of 130 mm, and standard balancing helps limit residual vibration during acceleration and deceleration. The motor is supplied without a blocking brake, so holding force must come from an external mechanism when the drive is de-energized. It uses a plain shaft with a shaft seal to help protect the internal bearings from contamination, and the shaft end is provided only on side A.

Power and feedback conductors terminate in a connector mounted on the end bell. With the cables exiting to the right, this orientation can simplify routing when multiple axes are installed side by side in narrow machine layouts. Rotor position is reported through digital servo feedback (DSF), enabling high-resolution current and velocity loops without auxiliary encoders and giving the controller direct feedback from the motor. The housing follows the series standard form, which keeps the external arrangement suitable for compact multi-axis assemblies and adjacent mounting surfaces.
