1FK7042-2AC71-1RH1-ZJ37 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AC71-1RH1-ZJ37 is a compact and powerful synchronous servo motor engineered for precision motion control and superior energy efficiency. This high-quality motor offers 0.59 kW of rated power at 2000 rpm, operating on a 600 V DC supply. With a torque of 3 Nm at 100K and an integrated 20-bit + 12-bit multi-turn absolute encoder with Drive-CLiQ interface, it ensures exceptional position and speed accuracy in all dynamic industrial applications. The model features a smooth shaft, IP65 protection, and an integrated holding brake for secure operation. Its naturally cooled IMB 5 (IM V1, IM V3) design supports flexible mounting orientations and reliable long-term performance.

Overview

The SIMOTICS S-1FK7 motor series represents the new generation of compact, permanent-magnet synchronous motors built for maximum adaptability and performance. Designed for use with SINAMICS S120/S220 drive systems, these motors form a robust, high-functionality servo solution that meets the continuously rising demands of modern machine engineering. Their integrated encoder systems ensure precise feedback for both speed and position control. With a cooling method based on natural convection, heat dissipation is optimized through the motor’s surface, eliminating the need for external cooling devices and improving overall efficiency. High overload capability guarantees reliable operation even under heavy load conditions, ensuring consistent productivity in demanding applications.

Benefits

• Compact structure with exceptionally high power density for space-saving installation.
• Versatile configuration suitable for a wide range of industrial applications.
• High dynamic response with minimal rotor inertia for fast acceleration.
• Stable closed-loop control even under varying load conditions.
• Minimal setup and calibration time with simplified disturbance compensation.

Application

The 1FK7042-2AC71-1RH1-ZJ37 motor is widely used in various sectors including machine tools, robotics, and automated handling systems. It also performs effectively in wood, glass, ceramics, and stone processing, as well as packaging, plastics, printing, and textile industries. Its integrated planetary gearing system (ALPHA SP+, SP 100S-MF2, two stages, ratio 50:1, without feather key) enhances torque transmission efficiency and mechanical precision, making it ideal for high-precision motion control tasks. With consistent accuracy and robust build quality, this SIEMENS motor guarantees long operational life and reduced maintenance downtime.
