36 Nm at 2000 rpm, 5.24 kW — and the line is winding down
The 1FK7103-5AC71-1...: The 1FK7103-5AC71-1 is a SIMOTICS S 1FK7 Compact synchronous servo motor rated 36 Nm continuous at 2000 rpm with a 5.24 kW shaft output in naturally cooled service — the headline numbers that decide whether it covers the axis you're trying to keep alive. Its is recorded as eol_hot, so factory-new stock is past and the supply path now runs through independent channels rather than the standard Siemens price book.
What the housing and connector tell the installer
Mounting is IM B5 (also IM V1 and IM V3), and the power/signal connector plugs through a rotatable 270° outlet — useful when the cabinet layout forces the cable entry sideways and the alternative is a cable gland that fights the bend radius. Naturally cooled (no fan cowl) means the 5.24 kW figure assumes the motor body can shed its losses to the flange and surrounding structure; on a machine with restricted airflow or a heat-soaked enclosure, the continuous torque drops well before the nameplate number does.
