Product Description:

The MDD025A-N-100-N2K-040GR0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It uses size 025 and the short A-length housing in a standard enclosure. Classified as a motor for digital drive controllers, it delivers precise rotary motion to light automation axes, pick-and-place heads, and labeling spindles where space is limited and rapid speed changes are required. It is intended for precise start-stop motion and stable speed control on small-format equipment.

At standstill the motor can supply 0.33 Nm of continuous torque, enough to hold tooling or small loads without overheating. Its nominal speed of 10000 rpm supports fast cycle rates when paired with high-bandwidth drives. A centering diameter of 40 mm provides accurate mounting concentricity on flanges or adapter plates, which helps keep coupled parts aligned during high-speed operation. Power and feedback are routed through a single connector, which simplifies cable routing in compact machine layouts. Position data is returned through resolver feedback, giving the controller analog sine-cosine signals that remain reliable at elevated temperatures and high rotational speeds. The plain shaft design minimizes friction, and the motor does not include a side-B shaft extension, which helps keep the overall length short.

The motor uses standard balancing to reduce vibration at full speed. The electrical terminals face to the right side of the stator body, which can help keep cable runs clear of moving parts. An integrated absolute encoder is installed beside the resolver to provide a power-on position reference without homing moves. The front bearing region is protected by a factory-installed assembly with a shaft seal, allowing operation where oil mist or fine dust is present. The unit comes without a blocking brake, so parked holding torque must be provided externally when the axis is at rest.
