Product description

The Siemens 1FK7103-2AF71-1CB0 is a SIMOTICS S synchronous servo motor combining a multi-turn absolute encoder with a holding brake for advanced positioning and safety. It delivers 4.4kW of power, operates at 600V DC, and provides 36Nm of torque at 3000rpm. This naturally cooled motor is built to IMB 5 design standards, features a rotatable power connector, a 24-bit + 12-bit multi-turn absolute encoder (AM24DQI) with Drive-CLiQ interface, a shaft with feather key, a holding brake, and an IP64 degree of protection.

This motor is designed for complex automation tasks requiring both precise multi-revolution positioning and fail-safe holding capabilities. It is ideal for vertical axis applications, robotics, and automated machinery where the load must be secured and absolute position retained after power interruptions.
