Siemens 1FK7103-5AF71-1EB0 SIMOTICS S Servo Motor Absolute Encoder
Siemens SIMOTICS S synchronous servo motor 1FK7 Compact with absolute encoder.
The Siemens 1FK7103-5AF71-1EB0 is a SIMOTICS S synchronous servo motor from the 1FK7 Compact series, featuring an absolute encoder for precise position detection without requiring a reference run. This motor delivers 4.40 kW nominal power, 36 Nm nominal torque (100K), and runs at 3000 rpm, with natural cooling and IM B5 mounting. It includes a rotatable power/signal connector (270°), an ENDAT absolute encoder with 2048 P/REV resolution (ENCODER A-2048), a shaft with a fitted key and N tolerance, and a holding brake. Note that the absolute encoder causes a 10% performance reduction. The degree of protection is IP64.
This servo motor is ideal for applications demanding high accuracy and immediate readiness upon power-up, such as automated storage and retrieval systems, sophisticated CNC machinery, and high-precision pick-and-place robots where eliminating homing cycles is beneficial. The inclusion of a holding brake adds to its suitability for vertical axis applications.
