1FK7040-2AK74-1SG2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK74-1SG2 is a premium synchronous motor designed for high-performance motion control applications. As part of the renowned SIMOTICS S-1FK7 family, it delivers excellent torque precision, superior energy efficiency, and a compact mechanical design ideal for modern automation systems. Engineered with a rated power of 0.69 kW, 6000 rpm nominal speed, and IP65 protection, this motor ensures reliable operation in demanding industrial environments. Its natural cooling system enables consistent performance without the need for external cooling, while the rotatable power connector enhances flexibility in installation.

Equipped with a Pt1000 temperature sensor, the motor offers precise thermal monitoring and protection, extending operational lifespan and ensuring system stability. The 1FK7040-2AK74-1SG2 version features a smooth shaft with standard tolerance (N) and does not include a holding brake, which makes it an ideal solution for applications requiring free movement or torque-controlled operation. The integrated resolver provides reliable feedback for position and speed, making it compatible with advanced drive systems like SINAMICS S120 or S220 for seamless motion coordination and control.

Overview

The SIMOTICS S-1FK7 series consists of compact, permanent-magnet synchronous motors designed to meet the performance needs of next-generation machines. Each motor in this series is optimized for high torque density and operational efficiency. The wide selection of shaft types, encoders, and gear options allows the SIMOTICS S-1FK7 range to be adapted to diverse automation requirements. These motors support direct integration with SIEMENS drive systems, forming a powerful, intelligent, and efficient motion control solution. Designed for fanless operation, the motor dissipates heat through its housing, maintaining consistent temperature levels even during continuous operation.

Benefits

The SIMOTICS S-1FK7 line offers multiple advantages, including compact design for space-saving installation, versatility for universal use, and availability in numerous power ratings. The High Dynamic variants provide outstanding acceleration due to their low rotor inertia, while the High Inertia models deliver exceptional control stability for heavy or fluctuating loads. This motor series simplifies commissioning and minimizes optimization time, providing seamless integration with machine tools, robots, packaging lines, and more.

Applications

The 1FK7040-2AK74-1SG2 motor is ideal for use in machine tools, robotic systems, and material-handling equipment. It is also widely used in wood, glass, ceramics, and stone processing, as well as in packaging, plastics, textile, and printing machinery. Its balance of precision, durability, and flexibility makes it a reliable choice for OEMs and automation engineers seeking high-quality motion solutions.
