The SIEMENS SIMOTICS S 1FK7042-2AF21-1RB2 is a compact and efficient synchronous motor engineered for modern automation environments where reliability and performance are paramount. Delivering 0.82 kW of rated power and 3 Nm of torque at 3000 rpm, this naturally cooled design is ideal for high-precision motion control. It operates at UDC 300 V and features a rotatable power connector, ensuring flexible installation in diverse configurations.
Built to meet industrial protection standards of IP65 and IP67, the motor withstands harsh operating conditions while maintaining smooth performance. Equipped with an AM20DQI DRIVE-CLiQ encoder, it provides 20-bit absolute and 12-bit multi-turn resolution for exact feedback and consistent accuracy. The inclusion of a holding brake and feather-key shaft enhances stability and safety in applications requiring secure load positioning or controlled stops.
The SIMOTICS S-1FK7 family represents a new generation of permanent-magnet synchronous motors, combining compact dimensions with high power density. These motors are designed to integrate seamlessly with SINAMICS S120 and S220 drive systems, forming a powerful, flexible automation solution for motion-intensive applications. Their efficient design dissipates heat through the motor housing, eliminating the need for external cooling systems while maintaining superior overload capacity.
The SIMOTICS S 1FK7042-2AF21-1RB2 is widely used in machine tools, robotics, packaging, and textile industries. It also supports printing, plastics, and material-handling systems, offering reliable torque and speed performance for continuous or high-demand motion processes. Each unit is engineered to deliver long-term reliability, exceptional energy efficiency, and superior dynamic response in both single-axis and multi-axis drive systems.
