1FK7042-2AF21-1PA2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AF21-1PA2 is a precision-engineered synchronous servo motor designed for modern automation systems that demand exceptional reliability, speed, and performance. Delivering a rated power of 0.82 kW with a torque of 3 Nm and a nominal speed of 3000 rpm, this naturally cooled servo motor ensures efficient operation in compact installations. Its design IMB 5 (IM V1, IM V3) with flange 1 construction provides robust mechanical stability, while the integrated DRIVE-CLiQ interface allows seamless communication with SIEMENS SINAMICS drive systems. Equipped with a 2-pole resolver and a shaft with feather key (tolerance N), the motor offers outstanding positioning accuracy and smooth rotational dynamics for high-precision motion control.

Overview

The SIMOTICS S 1FK7 series represents SIEMENS’s compact line of permanent-magnet synchronous motors that blend high power density with superior dynamic response. These motors are engineered for flexibility and can be combined with SINAMICS S120 or S220 drive systems to create a powerful, coordinated automation solution. With several encoder and gearbox options available, the 1FK7 family provides adaptability for a wide variety of motion control tasks. Designed for natural convection, the heat generated during operation is efficiently dissipated through the motor housing, ensuring long-term stability and consistent performance even under heavy industrial workloads.

Benefits and Applications

The SIMOTICS S 1FK7 Compact motors enable space-saving installation thanks to their high power-to-size ratio, making them ideal for applications where footprint efficiency is critical. They are widely used in machine tools, robotics, packaging equipment, textile machinery, and precision material-handling systems. High Dynamic variants deliver exceptionally fast response due to low rotor inertia, while High Inertia types ensure robust control characteristics for operations with fluctuating or heavy loads. These design advantages minimize setup time and optimize energy usage, contributing to higher overall productivity and system reliability.

For industries working with wood, glass, ceramics, plastics, or paper, the 1FK7042-2AF21-1PA2 offers precise control and repeatable positioning essential for complex production sequences. Its IP65 degree of protection (DE flange IP67) provides reliable safeguarding against dust and moisture, ensuring stable performance in demanding industrial environments. As part of the SIEMENS SIMOTICS S portfolio, this motor embodies engineering excellence for precision automation.
