5.2kW Power 36Nm Torque 2000rpm Speed Multi-Turn Absolute Encoder Drive-CLiQ Interface Feather Key Shaft IP64 Protection

The Siemens 1FK7103-2AC71-1RA0 is a SIMOTICS S synchronous servo motor equipped with a high-resolution multi-turn absolute encoder for precise motion tracking over extended ranges. It features a 5.2kW power rating, 600V DC link voltage, and 36Nm of torque at 2000rpm. This naturally cooled motor adheres to IMB 5 design standards, includes a rotatable power connector, a 20-bit + 12-bit multi-turn absolute encoder (AM20DQI) with Drive-CLiQ interface, a shaft with feather key, and an IP64 degree of protection. It does not include a holding brake.

This motor is ideal for applications requiring continuous rotation and absolute position feedback without the need for homing cycles after power loss. Its multi-turn capability is beneficial in automated systems with large travel distances, such as sophisticated CNC machines, large-scale robotics, and advanced material handling equipment.
