1FK7042-2AK71-1RA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1RA1 is a high-performance synchronous servo motor engineered for precision, stability, and energy efficiency in demanding automation environments. Delivering a rated power of 0.94 kW and a nominal torque of 3 Nm, this motor is optimized for applications that require fast acceleration, precise positioning, and long-term reliability. Operating at 600 V DC with a base speed of 6000 rpm, it offers outstanding torque consistency and a compact footprint for flexible machine integration.

This exclusive SIEMENS design combines natural convection cooling and a rugged IMB 5 (IM V1, IM V3) construction, ensuring consistent performance in industrial conditions. The unit includes an AM20DQI absolute encoder with 20-bit single-turn and 12-bit multi-turn resolution via Drive-CLiQ interface, providing exceptional motion feedback for high-accuracy positioning tasks. The motor’s IP65 protection rating safeguards it against dust and moisture, making it ideal for continuous operation in automated production systems.

Overview

The SIMOTICS S 1FK7 series motors are compact permanent-magnet synchronous units designed to meet diverse automation requirements. Their modular structure allows integration with various gearboxes and encoder types, enabling tailored configurations for each application. When combined with the SINAMICS S120 or S220 drive systems, they form a high-performance drive solution offering excellent dynamics, precise control, and energy efficiency. Heat dissipation occurs through the motor surface, allowing reliable operation without external cooling systems.

• High power density for space-saving installation
• Wide selection of motor variants for universal applications
• High overload capacity and dynamic response
• Integrated encoder systems for flexible speed and position control

Benefits

These motors deliver outstanding control characteristics and minimal commissioning effort, making them suitable for high-precision automation tasks. The low rotor moment of inertia ensures rapid response for dynamic movement, while robust feedback systems maintain stability under variable load conditions.

Applications

• Machine tools and robotic systems
• Packaging, textile, and plastic processing machines
• Wood, glass, ceramic, and stone-working equipment
• Printing and auxiliary drive systems
