1FK7042-2AF74-1AA2 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with part number 1FK7042-2AF74-1AA2 is a compact, high-performance solution for modern industrial applications. This motor delivers a nominal power of 0.82 kW and features a rated torque of 3 Nm at 3000 r/min, making it suitable for precision-controlled machinery. Designed as a naturally cooled unit with construction type IMB 5 (IM V1, IM V3) and flange 1, the motor provides robust performance without the need for external cooling. Its integrated Pt1000 temperature sensor ensures safe operation under varying loads, while the rotatable incremental encoder (sin/cos 1 Vpp, 2048 S/R with C and D track) allows precise speed and position monitoring.

The SIMOTICS S-1FK7 motor is equipped with a feather key shaft with N tolerance and a high protection class of IP65 on the drive end flange and IP67 on the non-drive end flange. These features guarantee resilience against dust and water, making it highly reliable even in demanding industrial environments. The motor can be paired seamlessly with SINAMICS S120/S220 drives to create a flexible, high-functionality system for motion control applications.

Overview

SIMOTICS S-1FK7 motors are designed as compact permanent-magnet synchronous units suitable for a wide range of industrial tasks. Thanks to the diverse options of gearboxes and encoders, these motors can be customized for specific requirements while maintaining high efficiency. The broad product range allows adaptation to state-of-the-art machinery, meeting both dynamic and high-inertia operational needs.

High-dynamic variants of the motor offer exceptionally fast response due to low rotor inertia, while high-inertia models provide robust control for variable load conditions. All motors are designed for operation without external cooling, dissipating heat efficiently through the surface, and exhibit a high overload capability, making them ideal for continuous, demanding operation.

Applications & Benefits

The 1FK7042-2AF74-1AA2 motor is widely used in industrial automation, including machine tools, robotic handling systems, and packaging machinery. It is equally suited for woodworking, glass, ceramics, plastics, textile, and printing machines. Compact installation, high power density, and minimal commissioning requirements make it a versatile choice for universal applications. With precise integrated encoder systems, it ensures accurate position and speed control while reducing the effort needed for system optimization and disturbance compensation.
