Siemens 1FK7103-5AF71-1EG0 SIMOTICS S Servo Motor ABS Encoder
Siemens SIMOTICS S synchronous servo motor 1FK7 Compact with absolute encoder.
The Siemens 1FK7103-5AF71-1EG0 is a SIMOTICS S synchronous servo motor from the 1FK7 Compact series, featuring an absolute encoder for precise, maintenance-free positioning. This motor provides 4.40 kW nominal power, 36 Nm nominal torque (100K), and operates 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), and a plain shaft with N tolerance. This model is supplied without a holding brake, and has a degree of protection of IP64. A 10% performance reduction is noted due to the absolute encoder.
This servo motor is suitable for applications requiring accurate, absolute position feedback without the need for homing cycles, and where a holding brake is not required. Examples include high-speed conveyor systems, packaging machinery, and printing presses where continuous, precise motion is essential.
