Sizing the 0.75 kW axis
The Siemens 1FL2306-1AC01-1MB0 is a SIMOTICS S-1FL2 low-inertia servo in the 65 mm shaft-height frame, rated 0.75 kW at 400 V 3AC supply with a rated speed of 2000 rpm and a continuous torque of 3.58 Nm — adequate for mid-range dynamic axes in packaging, small gantries, and pick-and-place cells where the load inertia sits in the same order of magnitude as the rotor. Stall torque is listed at 3.7 Nm, so the motor delivers roughly 3% peak overhead above its continuous figure — enough margin for short accel pulses without forcing a jump to the next frame size. Built-to-order configuration: keyed shaft (tolerance N), no holding brake, and an angular connector (AM21bit) for the power and feedback cables. The AM21bit encoder feedback resolves single-turn absolute position, which matters for machines that power up needing absolute axis reference without a homing routine.
Environment and mechanical fit
Sealing is IP65 with an oil seal at the shaft exit, meaning the motor tolerates dust ingress and low-pressure water jets — adequate for cabinet-internal mounting or washdown-adjacent machine frames, but not for direct food-zone spray. The oil seal specifies the lube-compatible duty; a dry-running application should confirm seal material against the media. At 65 mm shaft height this frame typically bolts to a standard servo mounting footprint; the keyed shaft (not a plain or keyed-plus-D-cut combination) accepts standard couplings and pinions. Without a holding brake, vertical axes need a regeneration-to-stop sequence or a mechanical brake elsewhere in the drivetrain before power removal.
Drive pairing and commissioning notes
The product description names SINAMICS S200 as the matching drive — pairing the S-1FL2 motor with the S200 line is the configuration Siemens specifies, so the encoder protocol, power connector keying, and parameter set are designed to plug straight into that drive's auto-configuration rather than requiring manual motor-data entry. Single-piece order quantity and product class C (built-to-order, non-returnable) means each unit ships against a fresh production order — the BOM line should be locked before the RFQ goes out, and stocking for spares carries an inventory commitment, not a return-credit option.
Compliance and lifecycle status
Compliance posture: RoHS conformity declared since 2018-01-01 and REACH Article 33 candidate-list disclosure applies — these travel with the shipping documentation so the procurement file and any export paperwork carry the substance-compliance trail the buyer needs for EU-destined builds.
