1FK7042-3BK71-1CG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-3BK71-1CG1 is a high-precision synchronous servo motor engineered to deliver outstanding performance and efficiency in advanced automation systems. With a rated power of 0.94 kW and a rated speed of 6000 rpm, this model offers a torque of 3 Nm (100 K) while operating at 600 V DC. Its naturally cooled IMB 5 construction with rotatable power connector and smooth shaft ensures reliable operation and flexibility for a wide range of motion-control applications.

Equipped with an integrated 24-bit + 12-bit multi-turn absolute encoder featuring DRIVE-CLiQ interface (AM24DQI), the 1FK7042-3BK71-1CG1 provides precise feedback for both speed and position control. The compact, robust design with IP65 protection makes it ideal for demanding industrial environments where accuracy, durability, and minimal maintenance are essential. This motor belongs to the SIMOTICS S High Inertia (HI) series, combining exceptional stability with smooth dynamic behavior for optimal machine performance.

Overview

The SIMOTICS S-1FK7 series represents the next generation of compact permanent-magnet synchronous motors developed for universal automation. When paired with SINAMICS S120 or S220 drive systems, these motors form a powerful, flexible system with seamless communication and high functionality. Designed for operation without external cooling, they efficiently dissipate heat through the motor surface, ensuring long-term reliability even in continuous-duty environments.

• Extremely compact design with high power density for space-saving integration
• High overload capacity with excellent thermal management
• Integrated encoder options for enhanced control precision
• Available in multiple variants to match specific load dynamics

Benefits

The 1FK7042-3BK71-1CG1 offers several operational advantages. Its High Inertia design provides stable closed-loop control even under variable load conditions, reducing setup and optimization time. The rotor’s low moment of inertia supports rapid response and smooth acceleration. Together, these features make this SIEMENS motor ideal for precision tasks requiring both accuracy and adaptability.

• Reliable performance for continuous operation
• Minimal commissioning effort due to integrated encoder feedback
• Excellent compatibility with existing automation infrastructures

Applications

Typical applications include machine tools, robotic systems, packaging machinery, printing equipment, and production lines in plastics, textiles, and glass manufacturing. Wherever precise positioning and motion control are required, the SIMOTICS S 1FK7 series delivers consistent, efficient, and intelligent motion performance.
