Lifecycle and sourcing status — still in active production
The 1FL6054-2AF21-0AG1 carries a lifecycle stage of 'current' — meaning Siemens still produces it as an active catalog item. No end-of-life notice, no last-time-buy clock.
Rated 2 kW at 3000 rpm with a continuous stall torque of 6.37 Nm — that torque figure is the same as the rated torque (M0 = MN), so the motor delivers full rated torque across the speed range without a constant-torque derating curve. The 50 mm shaft height places it in the compact frame class, typical for pick-and-place, labelling, or small conveyor axes where panel space is tight. The incremental encoder is TTL 2500 lines per revolution — that gives a native resolution of 10,000 counts per rev after quadrature decoding. For applications needing absolute position on power-up, this encoder requires a homing cycle; it is the right choice when the controller handles the reference move and the budget does not stretch to a multi-turn absolute encoder. IP65 rating with the supplied sealing ring means the motor body and shaft seal withstand washdown environments — food processing, packaging lines, or any area where hoses are used. The plain shaft (no keyway) and no holding brake keep the rotor inertia low, which matters for rapid acceleration/deceleration cycles; if the axis needs to hold position power-off, an external brake or a motor with an integrated brake would be needed.
Drive compatibility — mates with SINAMICS V90
Siemens explicitly lists this motor as compatible with the SINAMICS V90 converter series. That means the motor cable pinout, encoder feedback wiring, and parameter sets are pre-configured in the V90 drive firmware — no manual tuning of encoder resolution or motor inductance tables. For a retrofit into an existing line that already runs V90 drives, this motor drops in without re-engineering the drive cabinet.
