Description
The Siemens 1FK6083-6AF71-1TH0 is a powerful synchronous servo motor from the 1FK6 family, built for demanding servo-driven automation tasks like CNC machines, robotics, packaging, and heavy-load motion control. As a 6-pole AC servomotor, it offers stall torque of 16 Nm, rated torque around 10.5 Nm, and runs at a nominal speed of 3000 rpm (with capability to operate under varied load conditions).
The motor is naturally cooled (no fan required), reducing maintenance needs and improving reliability in industrial environments. Mounting is via IM B5 flange (V1 / V3), with a smooth plain shaft (tolerance N), suitable for coupling via external servo drives. The power and signal connectors are designed to be rotated up to 270°, facilitating flexible cabling and installation in tight spaces.
For positional control and feedback, the motor typically uses an incremental encoder (2048 pulses/rev) according to some vendor spec lists. A built-in holding brake provides safety and load-holding when power is off — useful for vertical axes or heavy loads. The motor’s IP64 protection class ensures dust- and splash-resistance, helping maintain performance and longevity in industrial settings.
With a hefty yet manageable weight (~ 18.4 kg), the 1FK6083-6AF71-1TH0 is meant for medium- to heavy-duty motion loads where high torque, reliability, and robust installation flexibility are required.
