5.2kW Power 36Nm Torque 2000rpm Speed Integrated Holding Brake 20-bit Absolute Encoder Drive-CLiQ Interface IP64 Protection

The Siemens 1FK7103-2AC71-1QH0 is a SIMOTICS S synchronous servo motor featuring integrated holding brake functionality for safety and positioning applications. It offers a power rating of 5.2kW, operates at 600V DC, and delivers 36Nm of torque at 2000rpm. This naturally cooled motor is designed to IMB 5 standards, includes a rotatable power connector, a 20-bit single-turn absolute encoder with Drive-CLiQ interface, a smooth shaft with N tolerance, and an IP64 degree of protection.

This motor is ideal for applications where precise positioning and fail-safe holding are required, such as vertical axis applications, robotic end-effectors, or any scenario where the load must be safely held in place when power is removed. Industries benefiting from this feature include material handling, packaging, and machine tool manufacturing.
