1FK7042-2AK71-1QH1-ZJ03 SIEMENS Exclusive SIMOTICS S Synchronous Motor with Planetary Gearing Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1QH1-ZJ03 is an advanced synchronous motor engineered for high-precision industrial automation. Delivering a rated power of 0.94 kW and 3 Nm torque, it operates at 6000 rpm with natural cooling and features a compact IMB 5 flange design. Its rotatable power connector and integrated 20-bit single-turn absolute encoder with Drive-CLiQ interface ensure accurate speed and position feedback for seamless integration into sophisticated motion control systems.

Designed to provide stable performance and energy efficiency, this SIMOTICS S 1FK7 motor is ideal for demanding automation environments where reliability and compactness are essential. The included ALPHA SP+ SP 075S-MF1 planetary gearing (1 stage, ratio i = 5, with feather key) provides outstanding torque transmission and mechanical precision, enabling smooth operation even under variable loads. With IP65 protection and robust construction, the motor withstands harsh industrial conditions while maintaining long service life.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ most versatile line of permanent-magnet synchronous motors. Compact dimensions, a variety of encoder options, and compatible gear units allow these motors to adapt perfectly to a wide range of industrial applications. When paired with the SINAMICS S120 or S220 drive systems, they deliver superior dynamic response and precise control. Their self-cooling design efficiently dissipates heat through the surface, ensuring consistent performance and high overload capability without external fans.

Benefits and Applications

• Extremely compact construction with exceptional power density
• Excellent precision for automation and positioning tasks
• Optional encoders and gearing for flexible system design
• High torque stability and fast response for smooth operation
• Ideal for machine tools, robotics, packaging, plastics, textile, and printing machinery
