1FK7042-2AC74-1SB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S motor 1FK7042-2AC74-1SB1 is a premium-grade synchronous motor designed to deliver precise motion, high torque, and excellent durability for a wide range of industrial applications. This compact and naturally cooled motor provides a rated power of 0.59 kW and a rated torque of 3 Nm at 2000 rpm, offering exceptional performance and long-term reliability in demanding environments. Built to the highest standards, this model ensures accurate control and superior energy efficiency for automation systems that require consistent motion and stability.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ cutting-edge technology in permanent-magnet synchronous motors. These motors are engineered to combine efficiency, precision, and flexibility in one compact design. With numerous encoder, gearbox, and brake options available, the 1FK7 motors adapt seamlessly to the evolving needs of modern machinery. When paired with SINAMICS S120 or S220 drive systems, they form an intelligent motion solution that delivers high performance, advanced functionality, and minimal maintenance requirements.

Design and Performance

The 1FK7042-2AC74-1SB1 is designed with a rotatable power connector, multi-pole resolver, and a shaft equipped with a feather key for secure torque transmission. The integrated Pt1000 temperature sensor ensures precise thermal monitoring, while the holding brake provides additional safety during machine stops. With an IP65 protection rating, the motor is built for harsh industrial environments and offers exceptional resistance to dust and moisture. Heat dissipation occurs naturally through the motor’s surface, allowing efficient cooling without external fans or ventilation systems.

This SIEMENS motor combines compact dimensions with high torque density, making it ideal for space-restricted machine assemblies. The result is smooth operation, reduced vibration, and consistent torque output under variable load conditions — all of which contribute to extended machine life and optimized productivity.

Applications

Typical uses include precision automation equipment, machine tools, robotic arms, handling systems, packaging lines, textile machines, and various production systems requiring accurate rotational control. The robust design and adaptive functionality make it a preferred choice for integrators who prioritize quality, safety, and performance.
