It sits in the Servo Motors class: a brushless rotary motor paired with a Siemens drive (SINAMICS S120 line in the typical 1FK7 application) that closes the position loop, so the motor's torque rating and inertia class — not its connector alone — determine whether it drops into a given axis conversion or replacement job. ## Lifecycle read: EOL/HOT and what that means for the BOM The listed for this order code is EOL/HOT, which on a Siemens servo typically means the part is past active promotion and is being serviced through defined stock or last-time-buy windows rather than ongoing series production — the exact wind-down date and any official successor are not carried in this listing, so the procurement decision has to be made against the BOM line, not against a long production horizon. ## Fit on the machine: torque, speed, and the cooling constraint The 28 Nm / 100K figure is the thermal continuous torque ceiling with the standard 100 K winding temperature rise — the rating a sizing engineer works to when matching the motor to a load's RMS cycle, not the short-term peak that the drive will let the windings reach under acceleration. Natural cooling (no integrated fan) means the motor's continuous torque assumes a clean, unobstructed housing surface and the specified ambient envelope; a machine rebuild that buries the motor inside a cabinet or stacks it next to a heat source has to be re-checked against the derating curve, because forced-air equivalents carry the same 28 Nm with a smaller frame.","metaTitle":"Siemens 1FK7086-7AF7.-1...
