1FK7042-2AF21-1RA2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New
The SIEMENS SIMOTICS S 1FK7042-2AF21-1RA2 is a premium-quality synchronous servo motor engineered to deliver precision, reliability, and energy efficiency for advanced automation systems. Built for consistent torque and smooth performance, this model provides a nominal power of 0.82 kW with a rated speed of 3000 rpm and a torque of 3 Nm (100K). Operating at 300 V DC, it ensures stable operation and exceptional control for applications that demand high accuracy and long service life.
Designed with a naturally cooled, compact housing and featuring an IMB5 mounting configuration (IM V1, IM V3), this motor enables flexible installation across various machine designs. The power connector can be rotated for simplified wiring, while its absolute encoder system AM20DQI with 20-bit single-turn and 12-bit multi-turn resolution ensures exceptional feedback precision through the DRIVE-CLiQ interface. The shaft comes with a feather key (tolerance N) and no holding brake, optimized for environments requiring continuous, maintenance-free operation. The motor’s robust structure provides IP65 protection on the drive end and IP67 protection on the flange, ensuring resilience even under demanding industrial conditions.
Overview
The SIMOTICS S-1FK7 motor series from SIEMENS represents a compact range of permanent-magnet synchronous motors, offering flexible configuration options to fit a wide spectrum of automation needs. Available in different mechanical sizes and encoder versions, the series integrates seamlessly with the SINAMICS S120 and S220 drive systems, creating a powerful, highly responsive automation solution. Designed for operation without external cooling, heat is efficiently dissipated through the motor surface, maintaining long-term reliability and reducing system complexity.
Benefits and Applications
The SIMOTICS S-1FK7 family offers multiple performance classes — Compact, High Dynamic, and High Inertia — enabling engineers to select the best match for specific industrial applications. Its advantages include compact installation, outstanding dynamic response, and robust closed-loop performance even under variable load conditions. These motors are ideal for machine tools, robots, material handling systems, packaging, woodworking, textile, printing, and auxiliary axis control. Their efficiency, accuracy, and reliability make them a trusted choice for automation solutions requiring precise positioning and superior motion control.
