Definition and what this motor does
The 1FK7060-5AF71-1...: The Siemens 1FK7060-5AF71-1 is a SIMOTICS S 1FK7 Compact synchronous servo motor drawing 6.0 Nm of rated torque at 100K duty, 3000 rpm shaft speed, and 1.48 kW shaft power with natural convection cooling — sized as a compact mid-range drive for feed and auxiliary axes where a frame around 6 Nm is enough headroom for the inertial mismatch with the load. Mounted IM B5 (also valid in IM V1 and IM V3 per the variant), it carries a rotatable power/signal connector plug that swings through 270°, so the lead-out can be aimed away from a coupling or cable tray without rotating the housing itself — a small detail that matters when retrofitting a spare into a packed cabinet.
Fit checks before you commit the order
Naturally cooled — no integrated fan — so the rated 1.48 kW continuous output assumes the motor sits in free air with the air path the IM B5 face leaves open; pushing it into a sealed enclosure pulls the continuous figure down, and the derating should be sized off the heat sink the flange presents rather than the nameplate number. Servo motors in the 1FK7 Compact class pair with SINAMICS S120 drive line modules and similar Siemens drive controllers — specifying a spare means the resolver or encoder code on the back of the existing motor must be matched, since swapping encoder type (resolver versus absolute multi-turn) breaks the drive's commutation on first power-up.
