Siemens SIMOTICS S-1FK2 HD Servo Motor About

The Siemens SIMOTICS S-1FK2 HD Servo Motor, model 1FK2104-4AF11-1MB0, is a high-dynamic permanent-magnet synchronous servo motor designed for precise industrial automation and motion-control applications. It provides a static torque of 1.27 Nm, maximum torque of 3.75 Nm, and a maximum speed of 7,200 rpm. The motor delivers 0.40 kW at 3,000 rpm for 380480 V operation and 0.20 kW at 1,500 rpm for 200240 V operation. It includes an integrated holding brake, IP65 protection, and a D19 40 mm shaft with feather key. The motor features an AM22DQC absolute encoder with 22-bit single-turn and 12-bit multiturn resolution for accurate closed-loop position control. It uses DRIVE-CLiQ M17 connectivity and an M17 power connector. With a net weight of approximately 2.9 kg, this servo motor is suitable for machine tools, robotics, packaging machinery, material handling, precision assembly, and automated production systems requiring accurate positioning, fast dynamic response, and reliable operation.
