Siemens 1FK7 high-dynamic synchronous motor
The 1FK7034-5AK71-1LG2 is a Siemens 1FK7 high-dynamic synchronous servo motor — a compact, high-acceleration rotor designed to pair with a SINAMICS S120 drive block on motion axes where short cycle times matter more than continuous torque (cites:,). It sits in the Servo Motors category under Motors & Motor Controls, the same slot used for the rest of the 1FK7 compact range (cites:,).
End-of-life, hot phase — what that means for the BOM
For a buyer this is the moment to either commit to the last-time-buy quantity now or specify a supported replacement from the current 1FK7 successor family; the part remains serviceable in the field but the supply window is finite (cites:).
