Siemens 1FK7043-7AK71-1EH2 SIMOTICS S Servo Motor
Siemens 1FK7 High Dynamic servo motor with ENDAT absolute encoder and holding brake.
The Siemens 1FK7043-7AK71-1EH2 is a SIMOTICS S synchronous servo motor from the 1FK7 High Dynamic series, engineered for demanding motion control applications. This motor delivers 3.1 Nm of torque at a high speed of 6000 rpm, with a power output of 1.26 kW. It features natural cooling and is designed for IM B5 (V1, V3) mounting. The motor includes a rotatable power/signal connector and an ENDAT absolute encoder with 2048 P/REV resolution. It has a plain shaft with Tolerance N and a holding brake. The degree of protection is IP65 for the motor body, with the flange on the drive end rated IP67.
This servo motor is ideal for high-performance applications requiring fast acceleration, precise positioning, and secure holding, such as in robotics, high-speed automation, and specialized machine tools. The ENDAT absolute encoder provides highly accurate position feedback for complex motion profiles. Note the 10% performance reduction due to the absolute encoder.
