1FK7042-2AF21-1QB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor 1FK7042-2AF21-1QB2 is a precision-engineered compact motor designed for high reliability and performance in industrial automation. With a nominal power of 0.82 kW, 300 V DC rated voltage, and 3 Nm torque, this motor delivers smooth and consistent motion in demanding applications. Operating at 3000 rpm, it provides excellent control and energy efficiency while maintaining a naturally cooled design. Its construction type IMB 5 (IM V1, IM V3) with flange mounting ensures stable operation in varied orientations.

Equipped with an integrated absolute single-turn 20-bit encoder (AS20DQI) featuring DRIVE-CLiQ interface, the 1FK7042-2AF21-1QB2 enables accurate position feedback and synchronization with SIEMENS SINAMICS drives. The shaft with feather key ensures secure torque transmission, while the IP65 degree of protection on the drive end and IP67 on the flange provide superior resistance to dust, oil, and moisture. An integrated holding brake enhances safety and operational control, making this motor an ideal choice for automated systems that require precise stopping and positioning.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ commitment to innovation and compact efficiency. These permanent-magnet synchronous motors combine advanced control technology with robust mechanical design. When paired with the SINAMICS S120 or S220 drive systems, they form a highly dynamic, flexible, and powerful motion control solution suitable for modern machine generations. The built-in encoders ensure seamless closed-loop feedback, allowing for precise speed and position regulation without the need for external sensors.
