Siemens 1FK7105-5AC71-1DG0 SIMOTICS S Synchronous Servo Motor

Product Overview

The 1FK7105-5AC71-1DG0 is a SIMOTICS S synchronous servo motor from Siemens’ 1FK7 compact series. Siemens describes the broader 1FK7 family as a permanent-magnet synchronous servo platform known for compactness, ruggedness, high overload capability, rotatable connectors, and DRIVE-CLiQ integration, which gives this exact motor a very clear industrial identity from the start: it belongs in serious motion-control systems, not in generic motor replacement scenarios.

For the exact order number, the published product descriptions consistently identify this configuration as a 48 Nm motor in the 1FK7 compact range with natural cooling, IM B5 (V1, V3) mounting, incremental encoder 2048 p/rev, DRIVE-CLiQ interface, plain shaft, no holding brake, and IP64 protection. Reseller and portal descriptions also place it at 2000 rpm with approximately 7.75 kW rated output for this configuration.

Application Value

A motor with this profile is well suited to high-precision servo duties where torque density, communication quality, and installation flexibility all matter.

Siemens highlights the 1FK7 compact design as a universal motor for a wide range of applications and emphasizes rotatable connectors, ruggedness, and safe connection to the converter.

In practical engineering terms, that makes the 1FK7105-5AC71-1DG0 a natural fit for machine tools, converting lines, automation modules, servo-driven feed systems, and handling equipment where motion quality and panel efficiency both matter.

The application examples here are reasoned from Siemens’ published family characteristics and the confirmed order-specific configuration.

The 270° rotatable connector is a particularly useful detail in real cabinets and on crowded machine frames. It does not change the motor’s electrical identity, but it can materially simplify cable routing, service access, and the mechanical packaging of the axis.

On product pages, that is worth emphasizing because technical buyers often care as much about integration convenience as they do about torque or speed.

Integration and Replacement Perspective

Siemens also positions DRIVE-CLiQ as more than just a connector choice. On the 1FK7 platform, DRIVE-CLiQ supports motor- and encoder-specific data handling and helps optimize connection to SINAMICS systems.

That means the 1FK7105-5AC71-1DG0 should be treated as a system-specific motion component rather than as a generic AC motor with a convenient mounting flange.

For maintenance teams and machine builders, the practical lesson is straightforward: match the full order number, encoder type, shaft style, cooling concept, and drive architecture.

From a commercial standpoint, this is exactly the kind of Siemens motor buyers search by full part number because the surrounding system expects a very specific configuration. That makes the model particularly suitable for replacement projects, spare-parts planning, and premium motion platforms where preserving the original integration standard is more valuable than searching for a “close enough” alternative.

This is an inference grounded in Siemens’ documented 1FK7 system features and the exact order-specific description.
