MDD025B-N-100-N2K-040FB1
The MDD025B-N-100-N2K-040FB1 is a synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended to interface with digital drive controllers so that commanded current is translated into fast, repeatable rotation for light-duty positioning tasks in industrial automation, including small pick-and-place arms, labeling heads, and miniature conveyor stations. Because it works with digital servo controllers, the motor can be used where acceleration, deceleration, and stopping accuracy must remain consistent from cycle to cycle. The motor has a size of 025, which supports compact axis layouts where installation space is limited. Its nominal speed of 10000 rpm allows rapid indexing in small servo applications.
Mechanical integration uses a centering diameter of 40 mm, which aligns the motor face to precision gearboxes or mounting plates. Power and feedback cables exit on Side B, keeping the harness away from moving loads, and the sealed connector interface simplifies assembly in tight spaces. This cable orientation can also simplify routing when the motor is mounted close to guides, slides, or guarding. The B length version provides moderate stack height without changing the standard housing profile, and standard dynamic balancing helps reduce residual vibration during operation. At standstill, the motor can deliver 0.60 Nm of continuous torque, which suits low-inertia mechanisms. Rotor position is reported through an integrated absolute encoder, so position data remains available after shutdown.
A plain shaft without a keyway reduces coupling misalignment and supports press-fit pulley installation. During power-off, the built-in brake supplies 1.0 Nm of holding torque to help prevent back-driving on vertical or unbalanced loads. The motor is built without a shaft seal, and the output uses a single-ended shaft format rather than a rear auxiliary shaft. The absence of a shaft seal is suitable for clean, enclosed machine areas where external sealing at the motor shaft is not required. This arrangement keeps the drive end simple for compact servo axes and leaves the rear of the motor free of an additional mechanical output.
