1FK7044-4CH71-1RA0 SIEMENS Exclusive High-Performance SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7044-4CH71-1RA0 is an exclusive SIMOTICS S compact synchronous motor engineered for precision, reliability, and adaptability in demanding industrial applications. With a rated power of 1.4 kW, a supply voltage of 600 V DC, and a nominal speed of 4500 rpm, this high-performance motor delivers robust torque of 4.5 Nm while maintaining a naturally cooled design. The motor features IP64 protection for operation in harsh industrial environments, along with a rotatable power connector and a high-precision 20-bit absolute encoder plus 12-bit multiturn encoder with DRIVE-CLiQ interface for accurate positioning and speed control.

Overview

The SIMOTICS S‑1FK7 series represents a range of compact permanent-magnet synchronous motors designed for universal applications across multiple industries. Their compact dimensions allow for space-saving installation without compromising power density. These motors are particularly well-suited for integration with the SINAMICS S120 and S220 drive systems, enabling high-functionality systems that benefit from precision speed and position control. The range of available encoders and gearbox options ensures that the 1FK7044-4CH71-1RA0 can be customized for any specific application, meeting the evolving demands of modern machine generations.

Benefits

• High power density allows space-saving installation in compact machine designs.
• Universal application potential across multiple industrial processes.
• High dynamic response due to low rotor inertia, ensuring precise control in high-speed operations.
• Robust closed-loop control for high or variable load moments, minimizing commissioning overhead.
• Wide product range provides flexibility for both standard and specialized applications.

Applications

The 1FK7044-4CH71-1RA0 is ideal for:

• Machine tools requiring precise positioning and dynamic response.
• Robotic and handling systems demanding reliable torque control.
• Wood, glass, ceramics, and stone working machinery.
• Packaging, plastics, textile, and printing machines for industrial automation.
• Auxiliary axes and additional drive components within complex systems.

Designed for operation without external cooling, the motor dissipates heat efficiently through its surface, ensuring continuous performance. Its high overload capability makes it resilient under variable loads, while the fitted key on the shaft and FLANGE 1 compatibility provide easy integration. The motor’s robust design ensures long-term reliability, reducing maintenance intervals and operational downtime.
