Series and what slots this motor fills
The Siemens 1FL2102-2AG00-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family built to pair with the SINAMICS S200 drive platform, sized at shaft height 20mm with a 200V 3AC supply and a 50W continuous power rating at 3000 rpm rated speed — the package that drops onto the cabinet shelf for small-format positioning axes where panel real estate is tight.
Torque, speed, feedback, and what the description actually says
Description-string ratings put standstill torque M0 and rated torque Mn both at 0.16 Nm, holding the motor in the very-low-inertia envelope typical of light load axes such as lab automation, small-format feeders, or auxiliary indexing stations where dynamic response matters more than raw torque. Feedback is the 21-bit hybrid encoder terminated to the AM21 connector — a single-cable feedback / power hybrid layout that simplifies the drag-chain harness versus separate resolver + power leads, though only against an S200 drive that reads that protocol variant. Shaft is supplied with key and N tolerance, without a holding brake; an axis that needs a fail-safe parked position must be sized using a separate brake motor from the 1FL2 family, not improvised on this order code.
Enclosure rating and the cabinet-side integration note
Protection class is IP54 without oil seal, which is enough for indoor cabinet-side mounting where the motor sits inside an enclosure or a sealed machine chassis but not for washdown, food-grade, or outdoor exposure — the integrator designing the housing must keep splashing coolant, cutting fluid, and direct jet spray away from the body and shaft seal area. One in the cabinet stance: for an S200 line that is already running one of these motors, holding a spare keeps a fault-axis swap inside a single maintenance window instead of a multi-week procurement hit when the line is down.
Lifecycle posture and compliance trail
Compliance documentation on the ledger is RoHS conformity since 01-01-18 and REACH Article 33 candidate-list information supplied via the manufacturer; export control flags AL:N / ECCN:N mean no special export licence gate applies to the standard commercial configuration.
