Where this motor drops on the machine
The 1FL2104-4AG00-1HC0 is a SIMOTICS S-1FL2 low-inertia servo motor out of the 1FL2 family that Siemens pairs specifically with the SINAMICS S200 drive line, sized at 200 V 3AC supply with a rated power of 1 kW and a rated speed of 3000 rpm. Both standstill torque M0 and rated torque Mn land at 3.2 Nm on a 40 mm shaft height — the equal M0/Mn figure means the motor is being run well inside its thermal envelope at the rated point, which is what you want on a positioning axis where the torque demand sits near the rated value most of the cycle. Feedback is a 17-bit absolute encoder fed through the AS-series hybrid connector, and the shaft ships with a key and N tolerance — a holding brake is not fitted on this build, so any axis that needs a passive stop at power-loss has to be specified into the next variant up the family. Sealing is IP54 without an oil seal, which is fine for a typical cabinet-fed axis in a clean assembly cell; an oil-sealed variant is the only way to push into a gearbox environment where oil mist reaches the shaft entry.
Ratings and what they actually decide
Pn 1 kW at Nn 3000 rpm on a 200 V 3AC bus maps cleanly onto the SINAMICS S200's 200 V class — pairing the motor to a 400 V-class drive would push the drive into field-weakening territory just to reach rated speed and is not the intended configuration. The 3.2 Nm continuous figure, combined with the 3000 rpm rated speed, sets the sizing ceiling for any axis sized from continuous torque rather than peak acceleration — most conveyor, indexing table, and small-format pick-and-place applications sit inside this envelope without derating. No holding brake means the motor holds position only while the drive is actively controlling the loop; for a vertical axis the BOM has to step up to a brake variant of the same 1FL2104 frame, otherwise gravity drop on power-loss is uncontrolled.
Compliance and the order class
The product is classed as built-to-order: it is manufactured per order, is not returnable for credit, and is not part of a reusable stock pool, which is the Siemens convention for the configured S-1FL2 / S200 motor-drive pairing. Lifecycle stage is recorded as current on the manufacturer's own listing, with no PCN or last-time-buy on the file — the part is sourced as an active, configured build rather than from a finished-goods inventory pool.
Carton and handling
Single-piece packaging in a 382 x 222 x 240 mm carton — sized for one motor plus the hybrid-connector mating half and documentation, not for multi-up shipping.
