Because the part is past its production run, pricing and availability move with each surplus lot that surfaces — independently held inventory with documentation traceable back to the original manufacturer packaging. That is the supply posture this page is written against: nameplate-faithful stock on the part, not factory allocation. ## Where 1FK7 servo motors sit in a machine Mounting follows the standard 1FK7 flange pattern; the motor pairs with a SINAMICS drive on the same SIZER/STARTER commissioning path as other rotors in the family — the encoder and brake options are encoded in the suffix string of the order code, not in separate accessories.","metaTitle":"Siemens 1FK7043-4CH71-1QA0 Servo Motor, 5.90 kgs","metaDescription":"Siemens 1FK7043-4CH71-1QA0 high-dynamic 1FK7 synchronous servo motor, 5.90 kgs.
