Backorder available · Factory lead time 2–3 weeks.
The SIEMENS SIMOTICS S-1FK7 synchronous motor, model 1FK7042-2AF21-1CH2, is a high-performance compact motor engineered for advanced automation applications. With a rated power of 0.82 kW, 300 V DC voltage, and a torque of 3 Nm at 3000 rpm, this motor delivers precise, reliable, and consistent performance. The naturally cooled design with IMB 5 flange ensures excellent thermal management without the need for additional cooling systems. Its smooth shaft with tolerance N and integrated holding brake provides enhanced stability and safety in demanding industrial environments.
The SIMOTICS S-1FK7 series is known for its compact permanent-magnet synchronous motors that can be tailored to specific machine requirements. These motors can be paired seamlessly with SINAMICS S120/S220 drives to create high-functionality systems. Integrated encoder systems, including the 24-bit absolute and 12-bit multi-turn encoder with DRIVE-CLiQ interface (AM24DQI), enable precise speed and position control. The high overload capability ensures the motor maintains stable operation even under fluctuating loads.
SIMOTICS S-1FK7 Compact motors are ideal for space-constrained installations while offering remarkable power density. High Dynamic variants deliver extremely fast response due to low rotor inertia, whereas High Inertia versions provide robust closed-loop control for applications with variable load inertia. Minimal setup and commissioning effort is required for compensating disturbances, making these motors highly efficient and user-friendly.
