SIMOTICS S synchronous motor 1FK7-CT Compact series Incremental encoder with DRIVE-CLiQ Holding brake included Plain shaft IP64 protection

Product description

The Siemens 1FK7040-2AK71-1AH0 is a SIMOTICS S synchronous servo motor, part of the 1FK7-CT (Compact) series. It offers a nominal power of 0.69 kW, a rated torque of 1.6 Nm (at 100K), and a rated speed of 6000 rpm, with natural cooling. This motor is designed for IMB 5 flange mounting and features a rotatable power connector. It is equipped with a SIN/COS 1VPP incremental encoder (2048 S/R) with C-and D-spur, and DRIVE-CLiQ interface. The motor has a plain shaft with tolerance N and includes a holding brake. The degree of protection is IP64.

This servo motor is suitable for a wide range of automation tasks requiring dynamic performance and precise control. The incremental encoder provides reliable feedback for continuous motion, while the holding brake ensures load stability. It is designed for use in machine tools, robotics, and automated production lines.
