1FK7042-2AK71-1RB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor 1FK7042-2AK71-1RB1 is a premium-grade compact drive solution designed for precise, efficient, and reliable industrial motion control. Engineered with cutting-edge German technology, this exclusive motor combines high torque density with low vibration and exceptional stability across demanding automation environments. It provides 0.94 kW of rated power and 3 Nm of continuous torque at 6000 rpm, making it ideal for machinery requiring smooth speed regulation and accurate positioning. Built for naturally cooled operation, the unit’s robust IMB 5 (IM V1, IM V3) construction and IP65 protection ensure consistent performance in harsh conditions.

With an integrated Drive-CLiQ interface and a 20-bit + 12-bit multi-turn absolute encoder (AM20DQI), this synchronous motor guarantees precise feedback for superior control and reduced commissioning time. The rotatable power connector and feather-key shaft design provide easy installation and mechanical adaptability, enabling seamless integration into complex drive systems or compact automation setups. Combined with its holding brake and high overload capability, the 1FK7042-2AK71-1RB1 represents reliability and operational efficiency for continuous industrial use.

Overview

The SIMOTICS S-1FK7 motor series is known for compact size, advanced performance, and compatibility with SINAMICS S120/S220 drive systems. These motors are engineered to achieve optimal efficiency without external cooling, dissipating heat through their sturdy surface housing. Depending on the application, the encoder configuration can be tailored for either speed or position control, providing flexibility for a wide range of automation needs.

• Compact, space-saving design with exceptional power density
• Universal applications across multiple industrial fields
• Reliable performance with minimal maintenance requirements
• Excellent control accuracy and rapid dynamic response

Applications and Benefits

Typical applications include machine tools, robotics, packaging, printing, and processing systems for wood, glass, ceramics, plastics, and textiles. The high-inertia design ensures smooth operation even under variable load conditions, while the low rotor inertia of dynamic variants supports exceptional acceleration. These features reduce commissioning effort and enhance system productivity, ensuring maximum uptime and consistent throughput.
