1FK7042-2AK71-1BB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor is an advanced, high-performance servo motor designed for precision motion applications that require efficiency, compactness, and reliability. With a rated power of 0.94 kW, nominal torque of 3 Nm, and a speed rating of 6000 rpm, this motor delivers consistent performance in dynamic industrial environments. It features natural cooling and a versatile IM B5 design (IM V1, IM V3) with a rotatable power connector for flexible installation in various machine setups.

This exclusive SIMOTICS S series model includes an integrated 24-bit single-turn absolute encoder with Drive-CLiQ interface (AS24DQI), offering precise position and speed feedback for closed-loop control systems. The motor shaft is equipped with a feather key and holding brake, ensuring stable torque transmission and secure stopping performance. Built to the IP65/IP67 protection standards, the motor is resistant to dust and water, making it suitable for demanding production environments where durability is essential.

Overview

SIMOTICS S-1FK7 motors represent the core of Siemens’ motion-control technology. These permanent-magnet synchronous motors combine compact construction with high power density, ensuring efficient operation and optimal energy use. Their modular design allows seamless integration with the SINAMICS S120 or S220 drive systems, creating a robust and intelligent motion platform that enhances performance across multiple industrial sectors. Each motor in the 1FK7 family supports a variety of encoder options and gearbox configurations, allowing complete adaptation to any automation requirement.

The 1FK7 series features a highly reliable thermal design that eliminates the need for external cooling—heat is dissipated efficiently through the housing surface. With exceptional overload capability and dynamic acceleration characteristics, these motors deliver precise, repeatable motion control even in demanding conditions. They are also engineered to support rapid start-up and minimal commissioning effort, reducing total setup time and maintenance costs.

Applications and Benefits

• Compact footprint enabling installation in space-restricted machinery
• Superior control accuracy and responsiveness for automation systems
• Compatible with SINAMICS S-series drive systems for high-functionality integration
• Ideal for machine tools, robotics, packaging, textile, printing, and auxiliary axes
• High overload capacity and smooth torque performance under variable loads
