Match this motor to the V70/V90 line
The 1FL6067-1AC61-2LB1 is a SIMOTICS S-1FL6 low-inertia servomotor from the 1FL6 family that pairs natively with the SINAMICS V70 and V90 drives. At a shaft height of 65 mm and an operating voltage of 3AC 400 V, it sits in the mid-frame slot of the family — small enough for machine tool axes and packaging heads, large enough for handling gantries. Continuous rated power is 2 kW at a rated speed of 2000 rpm, with a stall torque M0 of 15 Nm and a rated torque MN of 9.55 Nm. That M0/MN ratio of roughly 1.57:1 is the working window — peak torque is available above rated speed for acceleration ramps, while continuous work lands closer to the MN figure on a moving load.
Encoder, brake, and the 65 mm shaft height
The shaft carries a feather key with tolerance N and terminates in an angle plug for the power and feedback leads, matched to a 20-bit absolute encoder (12-bit multi-turn) so position is retained across power cycles without a homing routine. The holding brake is integrated — vertical-axis drops and Z-axis tool changes hold position when the drive stage is disabled, provided the brake is specified into the drive's brake-control logic. The housing carries IP65 with the sealing ring fitted, so the motor survives coolant splash and airborne oil typical of a machine-tool enclosure, but it is not rated for direct washdown — the customer-side cable gland and connector face carry the wet-end responsibility.
Lifecycle status — NRND, no successor on record
The product is flagged NRND — Not Recommended for New Designs. For running machines this is a service-spare posture: existing axes can be kept alive from the surplus channel, but a new machine build should plan for the supported successor in the 1FL6 family or a move to the current SIMOTICS S-1FK2 generation. No official successor is carried in the ledger, so any cross-reference must come from the Siemens configurator rather than from the record on this part. Compliance documentation on the line covers RoHS conformity since 01-01-18 and REACH Article 33 disclosure of substances of very high concern via the manufacturer's Reach Information page. Export-control classification is AL:N / ECCN:N, so the part ships without an export licence gate for the standard industrial destinations.
Sourcing posture for a service-spare buy
Quoted to order against the BOM — Group Code R220, Product Group 5183, manufactured to order with no return-for-credit pathway, packaged one per box at 466 × 264 × 290 mm. For an MRO buyer chasing a line-down spare, that means confirming availability against the RFQ rather than expecting shelf stock; the NRND status makes each confirmed quantity a planned allocation.
