What the motor is and how it pairs with the drive
The Siemens 1FL2104-4BF01-1HC0 is a low-inertia SIMOTICS S-1FL2 servomotor in the 1FL2 family built to match the SINAMICS S200 drive, running on a 400 V 3AC supply at a rated 1 kW and 3000 rpm nominal speed with 3.2 Nm continuous and stall torque at a 40 mm shaft height. Because the motor ships configured with an absolute encoder (AS17 bit) and a shaft key plus N tolerance, it drops straight into positioning axes where the integrator already has a SINAMICS S200 on the panel — the encoder feedback and connector type are pre-matched to that drive family.
Mechanical and sealing build
Holding brake is omitted, which suits vertical or horizontal axes where a separate mechanical brake on the gearbox handles the safe-stop duty, or where the drive's regenerative braking is sufficient. The housing carries IP65 protection with oil seal, and the motor exits via a hybrid connector — so the cable gland side is sealed for cabinet-through or machine-mount installations in oily machining environments, not for direct jet or submersion duty. Packaged as a single piece in a 315 x 182 x 172 mm box, the part ships as a one-off order unit rather than a bulk-stock commodity.
Compliance and documentation on record
RoHS substance restrictions have been declared compliant since 01-01-18, and REACH Article 33 candidate-list information is published by Siemens — the declaration pack covers the EU substance rules a tender requires. The part sits in Group Code R220 / Product Group X0DK and is classed as a made-to-order item that cannot be returned for credit — the PO has to commit on first order, not on trial.
