Servo motor on a high-dynamic axis
The part on the quote sheet is the Siemens 1FK7044-4CF71-1RB1, a 1FK7 high-dynamic synchronous servo motor used where an axis needs the responsiveness of a low-inertia rotor — typically feed drives, indexing tables, and high-acceleration pick-and-place modules driven from a SINAMICS or SIMOTION controller.
Hot-stock EOL flag drives the sourcing path
Lifecycle stage reads eol_hot, which means the line has been formally wound down by Siemens and residual stock is being drawn through independent channels rather than the factory schedule.
Handling and panel-side fit
It belongs to the Servo Motors class of the motors and motor controls family, sitting alongside the broader 1FK7 range of compact high-dynamic servomotors Siemens built around the same SINAMICS S120 drive platform.
