48 Nm at 3000 rpm — 8.17 kW compact servo on a spare-part line
The Siemens 1FK7105-5AF71-1... is a SIMOTICS S 1FK7 Compact synchronous servo motor rated 48 Nm at the 100K thermal class, 3000 rpm, and 8.17 kW naturally cooled — the kind of mid-range torque node a machine builder drops into a packaging, converting, or indexing axis where the higher-frame 1FK7 units are oversized but the 1FK7 Compact still has to hold 48 Nm through the dwell without slipping into the field-weakening region. It carries the IM B5 flange mounting style, and the power/signal connector is rotatable through 270° so the cable exit can be aimed at the cabinet entry without a right-angle adapter — a small point on the install but a real one on retrofit spindles where the original routing is constrained.
Sourcing posture for an eol_hot servo
The compliance pack expected on a Siemens SIMOTICS S motor — RoHS, REACH, and the CE declaration of conformity — is typically the procurement-quality buyer's first ask on an eol_hot servo, since the audit trail on the certificate of origin has to match the serial block shipped; requesting that documentation with the RFQ keeps the goods-receiving inspection from stalling the inbound.
