1FK7040-2AK74-1SB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK74-1SB2 is a premium-quality synchronous motor engineered for precision, durability, and efficiency. Designed as part of the SIMOTICS S-1FK7 series, this motor delivers superior performance in demanding automation and motion control environments. It offers a nominal power output of 0.69 kW at 6000 rpm, with a torque of 1.6 Nm under 100K conditions.

The motor operates with a 600V DC link voltage and is built for natural cooling, ensuring consistent operation with minimal maintenance requirements. Its IP65 degree of protection guarantees resilience against dust and water, while the DE flange provides IP67 sealing for extra durability. Equipped with a Pt1000 temperature sensor and a multi-pole resolver (P=4), this motor ensures precise thermal monitoring and smooth feedback control for optimal operation.

Overview

The SIMOTICS S-1FK7 family represents a new generation of compact, high-performance synchronous motors with permanent magnets. These motors combine cutting-edge technology with modular flexibility, allowing integration into diverse automation systems. When paired with SINAMICS S120 or S220 drives, they form a powerful servo drive system that offers outstanding precision, control, and energy efficiency. The design eliminates the need for external cooling, dissipating heat naturally through the motor surface, enhancing operational reliability and reducing maintenance overhead. Available with various encoder options and mounting configurations, SIMOTICS S-1FK7 motors are perfectly adaptable to a wide range of industrial applications.

Design and Benefits

These motors are distinguished by their high power density and compact form factor, enabling space-saving installation in complex machinery. The Compact series excels in universal applications requiring efficient performance in limited spaces, while the High Dynamic models feature low rotor inertia for rapid response and acceleration. The High Inertia variants provide superior stability under variable loads, ensuring smooth operation even in fluctuating conditions. Users benefit from easy commissioning, robust closed-loop control, and minimal adjustment time. These design advantages make the SIMOTICS S-1FK7 an ideal choice for modern automation tasks where precision, flexibility, and reliability are paramount.

Application

The 1FK7040-2AK74-1SB2 motor is widely used in machine tools, robotics, handling systems, and equipment for packaging, plastics, and textiles. It also performs exceptionally in applications involving wood, glass, ceramics, and stone processing, as well as printing machinery and auxiliary drive systems. Its versatility, combined with Siemens’ renowned engineering quality, ensures long-term performance and reduced downtime in industrial operations.
