Smooth Shaft for Flexible Coupling Multiturn Absolute Encoder Holding Brake for Position Control DRIVE-CLiQ Interface 2.7 kW Performance IP64 Rated

Product description

The Siemens 1FK7081-2AF71-1RH0 is a SIMOTICS S synchronous motor from the 1FK7-CT series, designed for high-performance automation. It delivers 2.7 kW of rated power at 3000 rpm and operates at 600V DC link voltage, with a nominal torque of 12 Nm (at 100K). This naturally cooled motor features IMB 5 (IM V1, IM V3) mounting with flange 1 and a rotatable power connector. It is equipped with a 20-bit + 12-bit multiturn absolute encoder (encoder AM20DQI) with a DRIVE-CLiQ interface. This model includes a smooth shaft with tolerance N, a holding brake, and an IP64 degree of protection.

This motor is suitable for a wide array of industrial automation applications, including servo-driven axes on machine tools, packaging machines, and robotics, where precise control and a smooth shaft interface are required for coupling.
