Description
The Siemens 1FK6042-6AF71-1TB0 is a robust, high-precision 6-pole synchronous servo motor from Siemens’ 1FK6 family, engineered for demanding motion-control applications. This motor offers a rated torque of 3.2 Nm at a rated speed of 3000 rpm, making it suitable for medium-power tasks in CNCs, robotics, packaging machines, or other automated systems.
To ensure precise position and motion control, the motor integrates a 2-pole resolver (P=1) feedback system — ideal for reliable commutation and feedback in industrial environments.
Installation flexibility is built in: the motor uses an IM B5 (V1/V3) mounting flange, a shaft with keyway (tolerance N) for secure coupling, and power/signal connectors that can be rotated up to 270°, aiding connection in tight or constrained spaces.
For safety and positional stability during standby or power-off conditions, the model includes a holding brake, and with IP64 protection and natural air cooling, it withstands typical industrial environments and dust/humidity exposure.
Though this unit has been declared discontinued (end-of-production as of 01/10/2016), it remains a solid option for retrofits, repairs, or legacy-system maintenance — or as a reference baseline if you look for comparable replacements.
