Overview

The SIMOTICS S 1FK7 motor series represents the latest generation of compact permanent-magnet synchronous motors. These motors are engineered for flexibility and can be adapted to numerous applications through various encoders, gearboxes, and design options. When paired with SINAMICS S120 or S220 drive systems, they form a seamless motion control solution that offers high-precision speed and position control. Thanks to their integrated encoder systems, SIMOTICS S motors guarantee excellent feedback accuracy for complex automation tasks. Their robust construction supports operation without external cooling—heat is dissipated directly through the housing surface, ensuring dependable performance and minimal maintenance requirements. With exceptional overload capacity and compact dimensions, the 1FK7 family is ideal for space-constrained installations where maximum reliability and precision are essential.

Benefits

The SIMOTICS S 1FK7 Compact motors deliver impressive power density for energy-efficient and space-saving configurations. They are versatile enough for universal applications across multiple industries. The High Dynamic variants provide rapid acceleration and deceleration with minimal rotor inertia—perfect for robotic and high-speed motion tasks. Meanwhile, High Inertia models ensure stable control where load changes frequently occur. This combination allows manufacturers to achieve superior performance, reduced commissioning time, and smooth operation even under dynamic load conditions.

Applications

Typical uses include machine tools, industrial robots, automated handling systems, woodworking, glass, ceramics, and stone-processing machinery. They are also commonly employed in packaging, plastic molding, textile production, and modern printing lines—applications where high responsiveness and precision are critical for productivity.
