1FK7043-4CK71-1RH2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CK71-1RH2 is a high-efficiency synchronous motor designed for precision-driven automation systems. Delivering 1.3 kW of power with a rated torque of 3.5 Nm and a nominal speed of 6000 rpm, this model provides exceptional performance under continuous operation. Its natural cooling system enhances reliability while maintaining low maintenance requirements. The unit features a plain shaft with holding brake, a rotatable power connector, and an absolute multi-turn encoder (AM20DQI) with 20-bit + 12-bit resolution using the DRIVE-CLiQ interface, ensuring outstanding position and speed control accuracy. With its IP65 motor housing and IP67 DE flange, the 1FK7043-4CK71-1RH2 offers enhanced protection for demanding industrial environments.

Overview

The SIMOTICS S-1FK7 motor range represents a new generation of permanent-magnet synchronous motors optimized for compact design, versatility, and efficiency. When paired with SINAMICS S120 or S220 drive systems, these motors form a highly dynamic motion control solution. Integrated encoder options provide reliable feedback for closed-loop speed and position control, while the natural convection cooling ensures continuous duty without the need for external fans. Thanks to their compact dimensions, these motors enable space-saving installation and high mechanical precision across automation systems of all scales.

Design and Benefits

• Compact high-performance design for tight installation spaces and optimized power output.
• Exceptional dynamic response due to low rotor inertia and efficient torque delivery.
• Versatile connectivity with rotatable power connectors and standard flange mounting (IMB 5).
• Enhanced protection with IP65 housing and IP67 DE flange for harsh industrial environments.
• Reliable integration with Siemens SINAMICS drives for smooth control and fast commissioning.

Applications

The 1FK7043-4CK71-1RH2 motor is ideal for machine tools, robotic arms, material handling, printing, textile machinery, and packaging systems. Its robust design and advanced encoder system make it suitable for both dynamic and high-inertia loads, ensuring stability and precision under variable operating conditions. Whether used in automation cells or high-speed production lines, this SIMOTICS S motor delivers long-term efficiency, low vibration, and exceptional control accuracy.
