1FK7043-4CH71-1CH1-ZJ22 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CH71-1CH1-ZJ22 is a premium synchronous servo motor engineered for high performance and precision in industrial motion control systems. Designed for demanding automation applications, this motor delivers 1.2 kW of power and a rated torque of 3.5 Nm at 4500 rpm. It operates at a DC link voltage of 600 V and features natural cooling, ensuring reliable thermal management without the need for external cooling systems. With its rotatable power connector, plain shaft with holding brake, and IP65 protection rating, the SIMOTICS S motor guarantees outstanding durability and operational safety even under continuous industrial use.

Equipped with a high-resolution AM24DQI absolute encoder offering 24-bit single-turn and 12-bit multi-turn capability via DRIVE-CLiQ interface, this model provides precise position feedback and superior control accuracy. The J22 configuration includes an ALPHA SP+ SP 075S-MF1 planetary gearing (1 stage, i=4, without feather key), designed to deliver smooth torque transmission and minimal backlash for demanding automation processes.

Overview

SIMOTICS S-1FK7 motors are advanced permanent-magnet synchronous motors developed to meet the increasing performance requirements of modern machinery. The combination of compact design, high power density, and multiple encoder options allows easy integration into diverse systems. When paired with SINAMICS S120 or S220 drive systems, they form a complete motion control solution offering dynamic responsiveness, energy efficiency, and simplified commissioning. The motor’s natural cooling concept enables efficient heat dissipation, while its rugged design ensures consistent operation even under high mechanical stress.
