1FK7042-3BK71-1RA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor (model 1FK7042-3BK71-1RA1) represents a new generation of compact, high-performance servo motors designed for precision and durability in modern automation systems. Delivering a rated power of 0.94 kW and a rated torque of 3 Nm at 6000 rpm, this motor provides smooth, efficient operation with outstanding responsiveness. The naturally cooled construction and IP65 protection ensure reliable performance even under demanding environmental conditions, while the flange-mounted IMB 5 configuration simplifies integration across a wide range of industrial machines.

Built for flexibility, this motor features a rotatable power connector and a 20-bit + 12-bit multi-turn absolute encoder with DRIVE-CLiQ interface, ensuring precise position feedback and smooth closed-loop control. The shaft with feather key and tolerance N design enhances mechanical compatibility and robustness, making it a perfect choice for applications requiring long-term accuracy and minimal maintenance. Engineered by SIEMENS, the SIMOTICS S series combines compact design, superior power density, and advanced encoder technology to maximize productivity and energy efficiency.

Overview

The SIMOTICS S-1FK7 motors are compact permanent-magnet synchronous motors optimized for versatility. They integrate seamlessly with the SINAMICS S120 or S220 drive systems, providing excellent motion control for automation, robotics, and CNC applications. With integrated encoder systems for speed and position feedback, the motors deliver precise performance without the need for external cooling. Their high overload capability ensures reliable operation across a variety of load conditions.

Benefits

• Space-saving configuration with exceptional power density for compact installations
• Universal compatibility with numerous industrial drive applications
• High dynamic response due to low rotor inertia for rapid acceleration and deceleration
• Robust closed-loop control for processes with high or varying load inertia
• Reduced commissioning and optimization effort, improving system efficiency

Applications

• Machine tools, robots, and automated handling systems
• Wood, glass, ceramic, and stone-processing machinery
• Packaging, plastic, textile, and printing industries
• Auxiliary or positioning axes requiring precision and repeatability
