1FK7042-3BK71-1RH0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7042-3BK71-1RH0 SIMOTICS S synchronous motor represents the next generation of high-performance servo technology. With a rated power of 0.94 kW and a rated torque of 3 Nm (100K), this model delivers exceptional precision and efficiency for demanding automation environments. Operating at a nominal speed of 6000 rpm and a DC voltage of 600 V, it offers smooth, quiet motion control with natural cooling and a compact IMB 5 (IM V1, IM V3) flange design. The rotatable power connector and integrated 20-bit + 12-bit multi-turn absolute encoder (AM20DQI) with DRIVE-CLiQ interface provide superior feedback and accuracy. Its smooth shaft, IP64 protection, and integrated holding brake make it highly reliable in challenging industrial conditions.

Overview

The SIMOTICS S-1FK7 series from Siemens sets a benchmark in compact, permanent-magnet synchronous motor design. Available in a wide range of torque and speed ratings, these motors combine high power density with outstanding precision. They can be paired seamlessly with SINAMICS S120 or S220 drive systems to form a powerful motion control solution. With integrated encoder systems for both speed and position control, the motors offer consistent performance even in applications requiring rapid acceleration and deceleration. Their natural cooling concept ensures efficient heat dissipation, making them maintenance-friendly and energy efficient while maintaining high operational reliability.

Design and Benefits

The SIMOTICS S-1FK7 motors are available in three performance classes: Compact, High Dynamic, and High Inertia. The Compact version enables space-saving installations with its high power density, while the High Dynamic variant provides an extremely fast response due to the motor’s low rotor inertia. The High Inertia version offers excellent closed-loop control, making it ideal for variable load conditions with minimal commissioning effort. Each variant is built for rugged industrial use, offering mechanical robustness and excellent vibration resistance.

Typical applications include machine tools, robotics, packaging, printing, and textile machinery. Additionally, these motors perform exceptionally well in glass, wood, and stone processing systems, as well as auxiliary axes where high precision and repeatability are critical.
