1FK7042-2AF21-1BA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AF21-1BA1 is a compact, high-precision synchronous servo motor engineered for demanding industrial applications requiring superior control accuracy and reliability. Designed with a naturally cooled configuration, this motor offers a rated power of 0.82 kW and a torque of 3 Nm at 3000 rpm. With its absolute encoder single-turn 24-bit system featuring the DRIVE-CLiQ interface, it delivers outstanding feedback precision and efficient communication with Siemens SINAMICS drive systems. The shaft with feather key ensures mechanical stability, while its IP65 protection class safeguards against dust and moisture for long operational life.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ excellence in servo technology. These permanent-magnet synchronous motors are compact yet powerful, designed to meet the growing performance requirements of modern industrial machines. When integrated with SINAMICS S120 or S220 drive systems, the 1FK7042-2AF21-1BA1 motor forms a dynamic motion control solution with precise speed and position control. The motor’s construction allows natural surface cooling, enabling consistent thermal management even in continuous-duty operations.

Design and Benefits

The motor’s robust IMB 5 (IM V1, IM V3) mounting configuration and rotatable power connector provide installation flexibility across multiple machine layouts. It offers an optimized combination of power density and size, making it ideal for space-restricted systems. The integrated encoder enhances synchronization and motion response, improving productivity in automation environments.

The SIMOTICS S-1FK7 product family includes various versions such as Compact, High Dynamic, and High Inertia motors—each designed to suit specific load and response requirements. Users benefit from high overload capability, minimal commissioning effort, and precise control performance. Typical applications include robotics, CNC machinery, packaging, printing, and material handling systems, where precision and reliability are critical.
