1FK7042-2AK71-1BB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor 1FK7042-2AK71-1BB1 is a high-performance servo motor designed for precision, speed, and long-term reliability. It delivers a rated power of 0.94 kW and a torque of 3 Nm at 6000 rpm, making it ideal for demanding industrial automation applications. This model features natural cooling with an IMB 5 construction type (IM V1, IM V3) and a flange-mounted design for secure installation. Its integrated Drive-CLiQ absolute encoder (AS24DQI, 24-bit single-turn) ensures precise position feedback and smooth control performance.

The motor includes a rotatable power connector and a built-in holding brake for additional operational safety. With IP65 protection, it offers exceptional durability in harsh environments, safeguarding components from dust and moisture. The shaft with feather key design enhances torque transmission efficiency, while the compact housing reduces space requirements in complex assemblies.

Overview

SIMOTICS S-1FK7 motors are premium permanent-magnet synchronous motors developed to meet the evolving needs of modern machine generations. They can be seamlessly combined with SINAMICS S120 and S220 drive systems to form a powerful motion-control solution. The integrated encoder options provide accurate speed and position control, supporting high-precision movements and efficient process automation.

• Compact, space-saving design with high power density
• Wide variety of configurations and encoder options
• Optimized for universal machine applications
• High overload capacity for dynamic operations
• Natural convection cooling – no external fan required

Benefits

The SIMOTICS S-1FK7 Compact motors offer exceptional versatility and ease of integration. They ensure smooth performance in machine tools, robotics, packaging, and textile production. High Dynamic variants deliver superior acceleration thanks to low rotor inertia, while High Inertia versions ensure robust closed-loop control for varying load conditions. This flexibility allows efficient tuning with minimal commissioning effort, reducing downtime and boosting productivity.

Applications

• Machine tools and automated assembly systems
• Robotics and material-handling equipment
• Wood, glass, ceramic, and stone processing
