The Siemens 1FK7040-5AK71-1FG5, part of the 1FK7 series, is a precision synchronous servomotor. This motor operates at a rated power of 0.69 kW, factoring in a 10% reduction, and offers a torque of 1.6 Nm. Designed for applications requiring high speed, it achieves an impressive rated speed of 6000 RPM.

The motor incorporates the DRIVE-CLiQ communication interface, facilitating seamless integration into control systems. Encoder feedback is provided by an absolute encoder with a resolution of 2048 pulses per revolution, ensuring accurate position tracking. Additionally, it allows for connector rotation up to 270°, adding flexibility in installation.

This unit is mounted in an IM B5 (flange mount) configuration but can also be adapted to alternate mountings such as IM V1 and IM V3. Its plain shaft, with tolerance N, supports standard mechanical interfaces. The motor relies on natural cooling to maintain operational efficiency.

The protective ratings for this servomotor are IP65 for the motor body and IP67 for the flange section, which makes it well-suited for robust industrial settings. The paint finish is RAL7016 in a gray color for aesthetic uniformity and environmental resistance. These features make the Siemens 1FK7040-5AK71-1FG5 an ideal choice for demanding applications.
