Spare-part servo for SINAMICS V70/V90 systems
The 1FL6044-1AF61-0LH1 is a Siemens spare-part servo motor from the SIMOTICS S-1FL6 series, designed for direct integration with SINAMICS V70 and V90 converters. It delivers 0.75 kW rated power at 3000 rpm, with a rated torque of 2.39 Nm and a peak torque of 3.5 Nm — the M0 figure that governs acceleration and deceleration in positioning cycles. The motor carries a 20-bit absolute encoder (12-bit multi-turn), which eliminates the need for a homing routine on power-up — the axis position is known immediately after the drive powers on. The holding brake holds the vertical axis at standstill when the drive is disabled.
IP65 and shaft-height fit
IP65 degree of protection with the sealing ring means the motor body withstands washdown and coolant splash — suitable for machine-tool and packaging lines where cutting fluids or wash cycles are present. The shaft height of 45 mm and plain shaft with tolerance N match the standard SIMOTICS S-1FL6 mounting footprint; the holding brake adds axial length, so the mating coupling and bracket must accommodate the brake housing. Operating voltage is 400 V 3-phase AC, the standard European industrial supply. The motor is compatible with SINAMICS V70 and V90 drives without an adapter cable — the connector pinout matches the drive's motor connector.
Sourced through authorized distribution channels against an RFQ. The spare-part designation means Siemens treats it as a serviceable unit — the full compliance documentation (RoHS, REACH, CE) accompanies the shipment.
