1FK7022-5AK71-1LG5 Siemens

The Siemens 1FK70225AK711LG5 is a compact, naturally-cooled permanent-magnet synchronous servo motor (series 1FK7) offering 0.38 kW power, 0.85 Nm static torque, and 6,000 rpm rated speed. It features an absolute multiturn encoder (20-bit single-turn + 12-bit multi-turn, Drive-CLiQ interface), IM B5 (V1 / V3) flange mounting, plain shaft (tolerance N), rotatable power/signal connector (270°) for flexible installation, and a robust IP65 (housing) / IP67 (flange) protection rating for industrial use

Description

The Siemens 1FK70225AK711LG5 servo motor is a high-performance, compact synchronous AC motor from the SIMOTICS S 1FK7 family, engineered for precise motion-control applications with limited space. It delivers 0.38 kW rated power and up to 0.85 Nm static torque, while running at a nominal speed of 6,000 rpm — making it well suited for high-speed, compact automation tasks.

For accurate feedback and control, the motor uses a high-resolution absolute encoder (20-bit single-turn + 12-bit multi-turn) with Drive-CLiQ interface, enabling precise position tracking and control in servo systems. Installation is simplified by the IM B5 flange (IM V1 / V3) design, a plain, keyway shaft (tolerance N), and a power/signal connector that can be rotated up to 270°, offering flexible cabling configuration in constrained setups.

Built for reliability in industrial environments, the housing of the 1FK70225AK711LG5 is rated IP65, while the flange end reaches IP67, providing strong protection against dust and moisture. Its compact design and high power-to-size ratio make it ideal for applications like machine tools, robotics, packaging systems, and other automation equipment where space is at a premium.
