1FK7 compact synchronous servo, 1.81 kg
The 1FK7022-5AK71-1TH3: 1FK7 compact units are permanent-magnet synchronous servos used in motion-control axes where the drive pairs with a Siemens SINAMICS S120 or similar controller, so the motor ships as part of a matched drive-and-feedback set rather than a stand-alone component.
Lifecycle: EOL hot, independent channel
With the part in hot phase-out, sourcing through independent distribution and surplus brokers is the standard procurement route — quoted against the BOM line and confirmed at RFQ rather than from a live factory schedule.
Sourcing posture and what to confirm
Buyers chasing 1FK7022-5AK71-1TH3 should be ready to provide the axis designation and existing drive firmware version on the RFQ, since 1FK7 compact motors must match the drive's motor ID database for commissioning to load the correct parameter set. No second source is published in the record, and the part sits on a single-brand supply path through Siemens; replacement is typically handled by a later 1FK7 variant or a SIMOTICS S-1FK2 successor once the spindle motor in question is rebuilt.
