What this motor is sized to do
The Siemens 1FL2204-4AF10-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the SH40 frame, rated 1 kW at 3000 rpm with 3.2 Nm rated torque and an identical 3.2 Nm stall torque, on a 400 V 3AC supply. It is built specifically as the 1 kW member of the 1FL2 family for direct pairing with the SINAMICS S200 drive — the AM21 hybrid connector on the rear routes power and the absolute 21-bit encoder feedback through one cable assembly, and the holding brake is integrated for vertical-axis or zero-load retention at standstill. Holding a continuous rating at 3.2 Nm from zero speed through to base speed is the headline engineering point of this frame: the rotor design does not need a constant-power field-weakening region to deliver full torque across the operating envelope, so positioning axes sized for peak short-term load still see the rated torque at the slowest move.
Mechanical and environmental envelope
Shaft height 40 mm with a keyed shaft to tolerance N, supplied as a single piece with holding brake; IP54 protection class, no oil seal, suits general-purpose cabinet interiors away from washdown exposure. Packaging unit is one piece per carton at 382.00 x 222.00 x 240.00 mm, RoHS-compliant since 01-01-18 and subject to REACH Art. 33 candidate-list disclosure; the listing is classified as product class C — built to order, non-returnable, so the BOM line should be firm before issuing the RFQ.
Sourcing the SH40 for an S200 build
Lifecycle reads as active build-to-order and the catalog group code R220 / product group X0DK flags it as a made-to-order servo; nothing in the record positions this motor against a pin-compatible successor, so the practical question for the spare-parts shelf is whether the line already standardizes on the SH40 1 kW frame before any cross-reference is requested. Build-to-order means lead time tracks the S200 cut and Siemens production scheduling rather than shelf stock — for a maintenance spare, push the order in advance of the scheduled maintenance window so the motor lands when the cabinet is open, not after.
