The 1FL6090-1AC61-0AG1 is a SIMOTICS S-1FL6 servo motor rated 2.5 kW at 2000 rpm, with a rated torque of 11.9 Nm and a stall torque M0 of 15 Nm — that stall figure is the torque available at zero speed for holding or starting a load, not the continuous rating. It runs on 400 V 3-phase AC and uses an incremental encoder TTL with 2500 incr/rev, which gives position feedback for closed-loop speed and torque control — the 2500-line encoder is standard for general-purpose servo applications where absolute position is not required. The shaft is plain (no keyway), tolerance N, and there is no holding brake — so if your application needs to hold position with power off, you will need to add an external brake or choose a variant with one.
IP65 and SINAMICS compatibility — deployment context
IP65 degree of protection with the sealing ring means the motor body is sealed against dust ingress and low-pressure water jets — suitable for washdown environments in food processing, packaging, or machine tool coolant splash, as long as the shaft seal and cable entry are also rated. It is explicitly compatible with SINAMICS V70 and V90 converters — that is the drive pair Siemens targets for this S-1FL6 series, so you do not need to hunt for a third-party servo drive; the tuning parameters and feedback interface are matched from the factory. Shaft height 90 mm and plain shaft tolerance N — the mounting flange and shaft dimensions follow the standard IEC frame size for this power class, so it should drop into existing mounts designed for a 90 mm servo frame.
