1FK7042-2AC71-1RH1-ZK23 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AC71-1RH1-ZK23 is a high-precision synchronous servo motor engineered for reliable performance in advanced industrial automation systems. With a rated power of 0.59 kW and a torque of 3 Nm at 2000 rpm, this model ensures smooth, accurate, and efficient operation across demanding applications. Designed with a naturally cooled IMB 5 (IM V1, IM V3) structure and an IP65 protection rating, it delivers consistent performance even in challenging environmental conditions. The integrated absolute encoder AM20DQI with 20-bit + 12-bit multi-turn resolution and Drive-CLiQ interface provides precise position feedback, supporting accurate motion control. The rotatable power connector, smooth shaft with tolerance N, and reliable holding brake make this motor highly adaptable and durable for long-term use.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ innovative generation of compact, permanent-magnet synchronous motors. These motors are built for flexibility, capable of pairing seamlessly with SINAMICS S120 or S220 drive systems for enhanced performance and control. Their integrated encoder systems allow precise speed and position regulation, ensuring stable operation in high-precision environments. The design emphasizes efficiency, with heat dissipation through the motor surface, eliminating the need for external cooling systems. With an exceptional power-to-size ratio and high overload capacity, the 1FK7-CT motors embody reliability, power, and control in one compact design.

Benefits

Key advantages include space-saving construction due to exceptional power density, compatibility with a wide range of machinery, and dependable performance in continuous operation. The SIMOTICS S-1FK7 High Dynamic variants deliver outstanding acceleration due to minimal rotor inertia, while the High Inertia types provide robust stability under variable loads. These motors minimize setup time and reduce commissioning complexity, enabling faster integration into modern production lines.

Applications

The 1FK7042-2AC71-1RH1-ZK23 motor is ideal for a wide spectrum of industries, including machine tools, robotics, packaging, plastics, and textile systems. It is also widely implemented in wood, glass, ceramics, and stone processing, as well as in printing and auxiliary machinery, where precise control and long-term reliability are essential. With its anthracite primer and paint finish (K23), this motor combines performance with durability and aesthetic consistency in professional installations.
