Product Description:

The MDD025B-N-100-N2K-040FD1 is a compact AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers where precise velocity and position loops are needed in pick-and-place axes, electronic cams, and light tooling stations. By integrating motor feedback, the unit supplies position information directly to the drive without requiring an external transducer. This makes the motor suitable for coordinated motion systems that need repeatable starts, stops, and short indexing moves. The integrated feedback arrangement also helps reduce cable routing complexity inside dense automation assemblies.

This model reaches a nominal speed of 10000 rpm, allowing short-stroke mechanisms and feeder rolls to cycle rapidly without additional gearing. At standstill it can deliver 0.60 Nm of continuous torque, which is suitable for holding light loads against friction or gravity while maintaining servo stiffness. A centering diameter of 40 mm provides the reference fit between the motor flange and the machine frame so alignment error is minimized. Position feedback is generated through resolver feedback, giving sinusoidal signals with good immunity to electrical noise over long cable runs. Power and feedback leads exit on side B, which permits rear-facing cable routing when the shaft points forward in compact enclosures. The motor is supplied with a connecting cable with a coupling unit, which simplifies connection at the machine.

For static holding or emergency stops, the integrated brake provides 1.0 Nm of torque so a vertical slide can remain locked when power is removed. Motion is transferred through a plain shaft, enabling backlash-free clamping hubs or precision collets to mount directly against the ground surface. The housing is delivered without a shaft seal, which reduces running friction and suits clean cabinet installations where liquid ingress is not a concern. This arrangement supports high-speed motion on low-inertia axes that use external couplings and do not require a sealed shaft interface. Because the shaft has no seal, the motor is better suited to dry, enclosed installations than to areas exposed to coolant or washdown.
