Product Description:

The MDD025A-N-100-N2G-040FB0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it provides high-speed rotary motion for positioning tasks in automated machinery and pick-and-place stations. Its plain shaft, lack of an integrated blocking brake, and resolver interface suit light-duty axes where tight control loops and minimal mechanical compliance are required. This layout also supports quick response in compact handling systems where short travel distances and repeatable motion are important.

At standstill, the rotor can continuously generate 0.33 Nm of torque, indicating the steady holding force available to resist external loads without overheating. During operation, the winding supports a nominal mechanical speed of 10,000 rpm, allowing rapid indexing cycles when paired with a matching drive. A centering diameter of 40 mm helps align the motor with gearheads or mounting flanges. The rotor and hub use standard balancing, which helps keep vibration within normal limits for small-frame machines. All power and feedback conductors exit on the B-side, so cable routing stays clear of the driven element on the opposite end.

Electrical termination is achieved through a keyed connector that mates directly with Rexroth cable sets, reducing wiring errors and preventing reverse polarity. Motion feedback is supplied through resolver feedback, providing rotor position data across the full speed range even in electrically noisy environments. Within the MDD family, this unit corresponds to size code 025 and the short body length denoted by code A, which helps lower mass moment of inertia during acceleration. The standard housing, plain shaft without a seal, and omission of the side-B shaft end keep the package compact for tightly spaced machine layouts. It also leaves more clearance around nearby tooling and cable runs in crowded axis assemblies.
