2.5 kW servomotor matched to SINAMICS S200 drives
The 1FL2310-0AC01-0SB0 is a SIMOTICS S-1FL2 servomotor rated 2.5 kW at 2000 rpm nominal speed, delivering 11.9 Nm rated torque and 12.6 Nm holding torque at standstill. The shaft height is 90 mm, which sets the mounting flange and pilot diameter for the machine interface. It carries a 21-bit absolute encoder (AS21) — no reference run after power cycle, so the axis position is known immediately on restart. The encoder is single-turn; for multi-turn applications, confirm the drive configuration supports the absolute position range. This motor is designed as the matched actuator for SINAMICS S200 servo drives. The drive parameters for current loop, speed loop, and encoder commutation are pre-configured when paired with the S200 series, reducing commissioning time.
IP65 enclosure, plain shaft, no holding brake
IP65 protection with an oil seal at the shaft exit means the motor withstands washdown and airborne particulates in food, packaging, or machine-tool environments. The oil seal adds drag torque at low speeds — budget 0.1–0.2 Nm for the seal friction at 2000 rpm. The shaft is plain (no keyway) with tolerance N per DIN 748. For direct coupling, use a clamping-type shaft collar or a keyless locking assembly. No holding brake is fitted — the motor relies on the drive's holding brake function or an external brake resistor for vertical-axis standstill. The angular connector exits at 90° to the motor axis, which keeps the cable bundle close to the motor body — useful in tight cable-tray routing or when the motor is mounted near a machine frame.
Active production, made-to-order class
The product class is C: manufactured or produced to order, which means it is not a stocked shelf item. Orders are non-cancelable and non-returnable per Siemens terms for this class. RoHS compliance is confirmed since 2018-01-01. REACH Article 33 candidate-list data is available from Siemens — request the current declaration at RFQ time for your downstream compliance file. Export control is AL:N / ECCN:N — no special license required for most industrial destinations. The packaging dimensions are 495 x 369 x 335 mm, single-piece quantity.
