1FK7042-2AC74-1TB1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AC74-1TB1 is a high-precision synchronous motor engineered for superior reliability and efficiency in demanding automation environments. With a rated power of 0.59 kW and a nominal torque of 3 Nm, it delivers accurate torque output across a wide speed range up to 2000 rpm. The naturally cooled design (IMB 5 / IM V1 / IM V3) ensures consistent thermal performance without external ventilation, reducing maintenance while maximizing service life. Featuring a robust IP65 protection rating, the 1FK7042-2AC74-1TB1 is ideal for industrial applications requiring durability and precision.

This model integrates a Pt1000 temperature sensor for reliable thermal monitoring, enhancing operational safety and efficiency. The rotatable 2-pole resolver enables precise feedback and flexible installation options, while the shaft with feather key and holding brake provide stable positioning in dynamic operations. Its compact, high-density design allows space-saving integration in automation systems where accuracy and responsiveness are critical.

Overview

The SIMOTICS S-1FK7 motor series combines compact size, energy efficiency, and dynamic performance. Each unit is designed for flexible adaptation using a wide range of encoders and gear units. When paired with SINAMICS S120 or S220 drive systems, these motors form a powerful and versatile motion-control solution. Their advanced encoder systems enable smooth speed and position control, offering excellent motion precision even under changing loads.

Designed for operation without external cooling, heat dissipation occurs through the motor housing for consistent thermal balance. The SIMOTICS S-1FK7 motors exhibit a high overload capacity, making them reliable choices for intensive industrial use. They are available in Compact, High Dynamic, and High Inertia variants to match different mechanical requirements.

Applications and Benefits

The 1FK7042-2AC74-1TB1 motor is widely used in machine tools, robotic systems, packaging lines, textile machinery, and automation applications where speed stability and precision are essential. Its low rotor inertia ensures quick acceleration and deceleration, while robust control properties maintain steady operation under varying load conditions. Key advantages include space-saving construction, long service life, and easy commissioning with minimal adjustment needs.
