Is this motor still on the line, or already past its sell date?
The 1FK70405AK711FG3: The Siemens 1FK7040-5AK71-1FG3 carries an EOL/hot lifecycle flag in the record — meaning the OEM has it staged for retirement but hasn't yanked it cold yet, so last-time-buy windows are the operative question for anyone holding a spare (cite:,cite:).
What the ratings tell you about the motor itself
Siemens lists the 1FK70405AK711FG3 as a 3-phase synchronous servo delivering 1.6 Nm continuous torque at 0.69 kW with a 6000 rpm ceiling — the small-frame 1FK7 profile, typically paired with a SINAMICS S110/S120 drive on positioning axes where the holding torque and inertia class matter more than raw power (cite:,cite:).
Where these small-frame SINAMIS servos actually run
Synchronous servos in this power band — roughly sub-1 kW — show up on feeder axes, small indexing tables, label-applicator stations, and packaging-machine cross-sealers where the drive closes a position loop with a resolver or encoder feedback channel (cite:,cite:,cite:).
