1FK7043-4CK71-1QA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CK71-1QA1 SIMOTICS S Synchronous Motor represents a new standard of performance, precision, and durability in industrial motion control. With a rated power of 1.3 kW and a nominal torque of 3.5 Nm, this naturally cooled motor delivers smooth, dynamic motion and reliable torque stability even in demanding environments.

Operating at a nominal speed of 6000 rpm and powered by a 600 V DC supply, it is ideally suited for applications requiring high accuracy and continuous duty performance. The motor features a rotatable power connector and an absolute single-turn 20-bit encoder with DRIVE-CLiQ interface (AS20DQI), ensuring accurate feedback and seamless integration with SIEMENS drive systems. Its shaft with feather key design, IP65 protection, and robust IMB5 mounting make it a dependable choice for industrial automation solutions.

Overview

The SIMOTICS S-1FK7 motor series from SIEMENS combines compact design with high power density, providing flexibility across a wide variety of machine applications. These permanent-magnet synchronous motors are engineered to meet the ever-increasing demands of modern machinery. When paired with SINAMICS S120 or S220 drive systems, they form a complete servo solution offering precision control, energy efficiency, and easy commissioning. The integrated encoder system supports both speed and position feedback, allowing precise synchronization and motion control. Designed for operation without external cooling, the heat dissipation occurs naturally through the motor housing, enhancing reliability and reducing maintenance requirements.
