Product description

The Siemens 1FK7022-5AK71-1LG0 is a SIMOTICS S Synchronous servo motor from the 1FK7 Compact series, designed for dynamic applications without a holding brake. It offers 0.85Nm of torque at 6000rpm with a 0.38kW power output and natural cooling. Key features include rotatable 270° power/signal connectors, IMB 5 design (IM V1, IM V3), Flange 1, and a 20-bit +12-bit multi-turn absolute encoder with Drive-CLiQ interface (AM20DQ). It has a plain shaft (tolerance N), no holding brake, and IP64 protection. A 10% derating applies due to the absolute encoder.

This servo motor is ideal for high-performance motion control in applications like high-speed pick-and-place, conveyor belt drives, and precision rotary indexing tables where continuous motion control is paramount and a holding brake is not required. The Drive-CLiQ interface ensures fast and reliable communication with compatible Siemens controllers.

Technical note

Expert tip

The plain shaft on the 1FK7022-5AK71-1LG0 requires a suitable coupling mechanism, such as a jaw or gear coupling, to transmit torque and accommodate potential shaft misalignment.
