1FK7040-2AK71-1UB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK71-1UB1 is a high-precision synchronous motor engineered for advanced industrial automation and motion control systems. Delivering a rated power of 0.69 kW at 6000 rpm with 1.6 Nm torque (100 K), this motor provides smooth, reliable, and energy-efficient operation. Its natural cooling design with an IP65 protection class ensures durability under harsh environments, while the integrated holding brake and DRIVE-CLiQ resolver interface guarantee optimal positioning and feedback accuracy. Designed for flexibility, the rotatable power connector and flange-mounted construction (IMB 5 / IM V1 / IM V3) allow easy integration into a variety of mechanical layouts.

Overview

The SIMOTICS S-1FK7 motor family represents a new generation of compact, permanent-magnet synchronous motors from SIEMENS. With a modular concept, broad encoder options, and compatibility with SINAMICS S120 and S220 drive systems, these motors deliver both performance and adaptability. Engineered for natural convection cooling, the 1FK7 series effectively dissipates heat through its housing, offering high overload capacity without external fans. This makes it an ideal choice for environments requiring minimal maintenance and continuous performance. The range supports a wide selection of gearboxes and encoders, enabling precise adaptation to specific automation requirements and ensuring long-term reliability in industrial applications.

Benefits

• Compact construction and exceptional power density for space-saving installations
• Broad range of motor variants suitable for universal applications
• High dynamic response enabled by low rotor inertia in High Dynamic models
• Stable closed-loop control even under variable load conditions
• Reduced commissioning and optimization time thanks to robust control design

Applications

This SIMOTICS S 1FK7040-2AK71-1UB1 motor is commonly used in precision-driven machinery such as CNC tools, robotic systems, and handling automation. It is equally suited for equipment in packaging, printing, wood and glass processing, plastics, and textile manufacturing. Its combination of compact size, dynamic control, and superior efficiency makes it a versatile choice for both high-speed and high-accuracy operations.
