1FK7042-2AF21-1BB0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AF21-1BB0 is a high-performance synchronous servo motor engineered for precision, efficiency, and long-term reliability in demanding automation environments. Designed for compact installation, it combines a naturally cooled configuration with a robust mechanical structure and superior energy efficiency. With a power rating of 0.82 kW, rated speed of 3000 rpm, and torque of 3 Nm (100 K), this motor delivers exceptional performance in applications requiring stable speed control and smooth dynamic operation. The unit features a DRIVE-CLiQ absolute single-turn 24-bit encoder (AS24DQI), ensuring precise position feedback for advanced motion control systems.

Overview

The SIMOTICS S-1FK7 family represents the next generation of compact permanent-magnet synchronous motors designed for integration with SINAMICS S120 and S220 drive systems. These motors are built to handle a wide range of industrial requirements, offering flexibility through selectable encoder systems, gearbox compatibility, and multiple cooling configurations. The design allows for operation without external cooling, with heat dissipated effectively through the motor surface for continuous operation under load. Each model is engineered to meet the growing expectations of modern machine builders, providing higher torque density and superior energy utilization.

Benefits

The SIMOTICS S-1FK7 series offers a compact footprint for space-saving installations and is ideal for universal applications. The High Dynamic variants ensure fast response with minimal rotor inertia, while the High Inertia models deliver smooth closed-loop control under fluctuating loads. These characteristics reduce commissioning time and simplify tuning, enabling seamless integration into industrial automation systems. The motors exhibit robust mechanical construction, high overload capacity, and exceptional reliability.

Applications

Typical uses include machine tools, robotic systems, packaging and textile machinery, printing units, and precision automation lines. The combination of compact design, versatile encoder interface, and consistent torque output makes this model a dependable solution for both new installations and system upgrades.
