Siemens 1FK7103-5AF71-1AH0 SIMOTICS S Servo Motor with Brake
Siemens SIMOTICS S synchronous servo motor 1FK7 Compact with holding brake.
The Siemens 1FK7103-5AF71-1AH0 is a SIMOTICS S synchronous servo motor from the 1FK7 Compact series, designed for applications requiring precise motion control and holding capability. It offers a nominal power of 4.40 kW, a nominal torque of 36 Nm at 100 Kelvin, and operates at a rated speed of 3000 rpm. This naturally cooled motor utilizes the IM B5 (IM V1, IM V3) mounting configuration and features a rotatable power/signal connector (270°). It is equipped with an incremental encoder (SIN/COS 1 VPP, 2048 P/REV) for accurate position feedback, a plain shaft with N tolerance, and includes a holding brake for secure positioning. The degree of protection is IP64.
This servo motor is well-suited for applications such as vertical axis movements in robotics, lifting mechanisms, machine tools, and any system where the load needs to be held in place when power is off or during controlled stops. The combination of an incremental encoder and a holding brake provides enhanced safety and control for dynamic tasks.
