1FK7040-2AK74-1SA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK74-1SA1 is a premium-grade compact synchronous motor designed for maximum reliability and energy efficiency in high-performance automation systems. With a rated power of 0.69 kW, a torque of 1.6 Nm (100 K), and a nominal speed of 6000 rpm, this model ensures smooth, precise operation under a wide range of industrial conditions. The motor features a 600 V DC power supply, natural cooling for maintenance-free performance, and a rotatable multipole power connector for flexible installation. Its resolver with P = 4 and integrated Pt1000 temperature sensor guarantee precise control, stable feedback, and extended service life in continuous-duty environments. Protected to IP65 standards, this motor offers robust durability even in challenging production settings.

Overview

The SIMOTICS S-1FK7 series represents the next generation of permanent-magnet synchronous motors, designed for compactness, flexibility, and long-term dependability. These motors can be seamlessly combined with SINAMICS S120 or S220 drive systems to create a powerful motion-control setup capable of handling demanding industrial tasks. Each motor integrates an advanced encoder system for precise speed and position monitoring, while its naturally cooled design ensures effective heat dissipation through the motor housing without the need for external cooling units. Thanks to their modular construction, these motors can be configured to meet various mechanical and electrical requirements across modern automation applications.

Design and Applications

The 1FK7 series offers several sub-variants to match unique application needs. The Compact version provides high power density in a small footprint, making it ideal for space-constrained installations. The High Dynamic models deliver rapid acceleration and deceleration due to an exceptionally low rotor inertia, while the High Inertia types ensure stable closed-loop performance for systems with fluctuating or heavy load conditions. This model is widely used in CNC machine tools, robotics, material-handling systems, woodworking, glass and ceramics processing, packaging, plastic manufacturing, printing, and auxiliary motion systems. Its efficiency, reliability, and mechanical precision make it an essential component in modern automation lines seeking enhanced productivity and reduced downtime.
