The stall torque (M0) is 3.5 Nm — this is the torque available at zero speed for holding or starting a load, and it's the figure to use when sizing the motor for a positioning axis that needs to hold position under power. The incremental encoder is TTL with 2500 increments per revolution — that's 10,000 quadrature edges per rev after the A/B channels are decoded, giving a position resolution of 0.036° per count. For a ball-screw axis with a 10 mm lead, that's 1 µm per count at the load — adequate for most pick-and-place and packaging applications. IP65 protection with the sealing ring means the motor body is dust-tight and protected against low-pressure water jets from any direction — suitable for washdown areas in food processing or packaging lines where the motor sees hose-down cleaning but not high-pressure spray. The sealing ring is a separate component that must be fitted at installation to maintain the rating. ## Mounting and drive pairing Shaft height is 45 mm with a plain shaft (no keyway) and tolerance N — this is a standard metric fit for a coupling or pulley with a clamping hub. The plain shaft means the torque is transmitted through the clamping force of the hub, not a key; verify the coupling bore tolerance matches the shaft diameter before assembly. Compatible with SINAMICS V70 and V90 servo drives — these are Siemens' compact, cost-optimized drive families for basic positioning and speed control in packaging, handling, and textile machinery. The motor cable and encoder cable pinouts must match the drive's connector layout; the V90 typically uses a 26-pin D-sub for the encoder feedback. No holding brake on this variant — the motor relies on the drive's holding torque at zero speed or an external brake to hold the load when power is removed. If the application requires a fail-safe hold on power loss (vertical axis, tool changer), order the version with the built-in holding brake or add an external spring-applied brake on the load side.","metaTitle":"Siemens 1FL6044-1AF61-0AG1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens 1FL6044-1AF61-0AG1 SIMOTICS S-1FL6 servo motor, 0.75 kW, 3000 rpm, 2.39 Nm, IP65, TTL encoder.
