MDD025A-N-100-N2G-040GF0

Length code “A” is the shortest standard frame length for size 025, meaning lower rotor inertia and more compact envelope, but less peak (overload) capability than longer (B, C) versions. It suits applications where space is constrained and torque demands are moderate.

This type ensures consistent shielding, connector reliability, and simplified installation; mismatched or long cables degrade signal fidelity in resolver feedback or increase power losses. Using proper coupling and keeping cable runs within spec helps avoid voltage drop or control instability.

The continuous torque at standstill specification assumes certain cooling conditions; since it lacks an integral brake or fan, heat dissipation depends on ambient temperature, enclosure design, and duty cycle. Excessive continuous loading without adequate cooling can lead to winding overheating or reduced motor life.

The code signifies: size 025, length “A”, “N-100” nominal speed 10000 min⁻¹, feedback “G” (resolver), centering diameter 040 mm, plain shaft with shaft seal (“G” in “GF0”), no blocking brake (“0” in last position). It lets you ensure the motor matches drive control firmware, mounting dimensions, and mechanical interfaces.

Without a side B shaft-end, options like dual shafted load attachments or accessories (e.g. encoders, gearboxes) are limited to one side, which may constrain layout flexibility. But it reduces complexity, sealing challenges, and cost in compact single-output designs.
