Product description

The Siemens 1FT6086-8SF71-4AG1 is a SIMOTICS S synchronous servo motor from the 1FT6 series, delivering 35 Nm of torque at 3000 rpm with force ventilation. This motor features an incremental encoder (sin/cos 1 Vss 2048 S/R) and a smooth shaft, making it ideal for applications where shaft keying is not required or desired. It has a Gamma sealing ring for IP65 protection and is designed for IM B5 (IM V1, IM V3) mounting with axial DE connector outlet. It does not include a holding brake. Vibration severity grade is N.

This servo motor is well-suited for a wide range of industrial automation applications requiring precise speed and position control, such as high-speed machinery, robotics, and advanced manufacturing systems. The smooth shaft allows for direct coupling or specialized hub connections.
