What this servo motor delivers on a motion axis
The 1FL6092-1AC61-0LB1 is a Siemens SIMOTICS S-1FL6 servo motor rated for 3.5 kW continuous power at 2000 rpm, with a peak torque of 22 Nm and a rated torque of 16.7 Nm — the M0 figure tells you the stall torque available for holding or acceleration at zero speed, while MN is the continuous torque the motor can deliver without exceeding thermal limits. It carries a 20-bit absolute encoder with 12-bit multi-turn resolution, meaning the drive knows the rotor position at power-up without a homing cycle, and the multi-turn count tracks absolute shaft position over 4096 revolutions — useful on axes where the load position must be retained after a power cycle. The motor is marked as a spare part, compatible with SINAMICS V70 and V90 drives, and includes a holding brake and a feather key on the shaft — the brake holds the vertical axis load when the drive is disabled, and the key transmits torque to the coupling without slipping.
Mounting and environmental fit
Shaft height is 90 mm — this is the dimension from the mounting foot to the shaft centreline, matching the standard frame size for this power class in the S-1FL6 family. The IP65 rating with sealing ring means the motor body and the shaft seal withstand washdown and dust ingress, so it can be mounted directly on a machine frame in a food-processing or packaging line without an additional enclosure. The 400 V three-phase winding is wound for 3 AC input, which is the standard European industrial supply. The holding brake is integrated — no external brake rectifier needed — and the encoder cable routes through a separate connector, keeping power and feedback wiring separated per EMC best practice.
