1FK7040-2AK71-1QH2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7040-2AK71-1QH2 SIMOTICS S synchronous motor is a high-precision drive solution designed for industrial applications that demand exceptional accuracy, reliability, and long-term durability. Engineered as part of the advanced SIMOTICS S 1FK7 Compact series, this motor combines high power density with a compact frame for efficient space utilization.

It operates at 600 V DC and delivers a continuous torque of 1.6 Nm (100 K) at a nominal speed of 6000 rpm. With natural cooling, IP65 protection, and a smooth shaft featuring tolerance N, it guarantees stable performance even in challenging industrial conditions. The integrated 20-bit single-turn absolute encoder with DRIVE-CLiQ interface (AS20DQI) ensures precise feedback for closed-loop control, while the rotatable power connector and holding brake enhance operational flexibility and safety.

Overview

The SIMOTICS S-1FK7 motors are compact permanent-magnet synchronous machines developed to meet the increasing performance requirements of modern automation systems. Their modular configuration allows flexible adaptation with various encoders, gearboxes, and mounting options, making them ideal for a wide range of mechanical and motion control tasks. When combined with the SINAMICS S120 or S220 drive systems, the 1FK7 series delivers superior dynamic response, smooth motion, and precise positioning for complex production environments. The motor’s surface-cooling design eliminates the need for external fans while maintaining a high overload capacity and steady thermal stability.

Benefits

The SIMOTICS S-1FK7 Compact motors offer space-saving installation and high power density for universal applications. Their flexible mounting design ensures easy integration into new or existing systems. The High Dynamic variants provide exceptional acceleration and response due to a low-inertia rotor, while the High Inertia types offer stable closed-loop control for applications with variable load moments. These motors significantly reduce commissioning time and simplify disturbance compensation, making them a preferred choice for automation designers seeking efficient and future-ready solutions.

Applications

• Machine tools and precision machining systems
• Robotics and automated handling systems
• Wood, glass, ceramics, and stone processing machinery
• Packaging lines and plastics production equipment
