1FK7 Compact series INCREMENTAL ENCODER SIN/COS 1 VPP 2048 P/REV 3000 rpm speed Plain shaft IP64 protection No holding brake

Product description

The Siemens 1FK7105-5AF71-1AG3 is a SIMOTICS S synchronous servo motor from the 1FK7 Compact series. It is designed for a nominal speed of 3000 rpm and offers 48 Nm of torque, with a power output of 8.17 kW, using natural cooling. The motor features IM B5 mounting and a rotatable power/signal connector. It is equipped with an INCREMENTAL ENCODER, SIN/COS 1 VPP 2048 P/REV. This model has a plain shaft with tolerance N and is specified as 'W/O HOLDING BRAKE' (without holding brake). The degree of protection is IP64, and it is finished in RAL7016.

This servo motor is ideal for high-speed, dynamic applications in industries such as packaging, material handling, and automation where precise motion control without the need for a holding brake is required. Its specifications support demanding operational cycles.
