1FK7042-2AF71-1RA1-ZY84 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor, model 1FK7042-2AF71-1RA1-ZY84, represents advanced performance and reliability for modern automation systems. With a continuous rated power of 0.82 kW, torque of 3 Nm (100 K), and a nominal speed of 3000 r/min, this naturally cooled synchronous servo motor ensures consistent efficiency in demanding industrial environments. Its rugged IMB 5 flange design, IP65 protection, and 20-bit + 12-bit multiturn absolute encoder with DRIVE-CLiQ interface make it ideal for precision control applications that require high stability and accuracy.

Designed for direct integration with SINAMICS S120 and S220 drive systems, this unit delivers exceptional synchronization, smooth torque output, and quiet operation. The rotatable power connector and shaft with feather key allow for flexible installation, while the motor’s robust thermal management and high overload capability support continuous operation under heavy load cycles. Built to deliver long service life, the 1FK7042-2AF71-1RA1-ZY84 is a cost-effective solution for machine builders seeking energy-efficient performance and compact design.

Overview

The SIMOTICS S-1FK7 series comprises compact permanent-magnet synchronous motors designed for precision automation. The product range includes numerous mechanical and electrical variants, enabling optimal adaptation to diverse machine concepts. Each motor incorporates high-resolution encoder systems for precise feedback and reliable position control, supporting both speed and torque-controlled operations. These motors are engineered for natural cooling through their surface, eliminating the need for external cooling fans and simplifying system configuration.

When combined with SINAMICS drive technology, the S-1FK7 line forms a complete, high-functionality motion control system. From packaging and robotics to printing and CNC applications, the S-1FK7 motors deliver stable dynamics and outstanding repeatability even under frequent start-stop conditions.
