1FK7044-4CF71-1CH0 SIEMENS Exclusive High-Performance Synchronous Motor Original Brand New

The SIEMENS 1FK7044-4CF71-1CH0 belongs to the SIMOTICS S-1FK7 series of compact synchronous motors, renowned for their precision, efficiency, and mechanical robustness. This model delivers 1.2 kW rated power, 4.5 Nm nominal torque at 3000 rpm, and operates on a 600 V DC bus. Designed with natural cooling and a rotatable power connector, it ensures optimal flexibility during installation. The integrated 24-bit + 12-bit multiturn AM24DQI encoder with DRIVE-CLiQ interface provides accurate position feedback for dynamic motion control. Featuring a plain shaft with tolerance N and a holding brake, the motor is protected to IP64 standard, guaranteeing durability even in demanding industrial conditions.

Overview

The SIMOTICS S-1FK7 motors represent the latest generation of permanent-magnet synchronous motors by Siemens, offering a perfect combination of compact dimensions and high power density. With various configuration options, these motors can be precisely adapted to different machine concepts, whether for automation, robotics, or precision equipment. When integrated with the SINAMICS S120/S220 drive systems, they form a powerful motion platform capable of superior speed and position control. Designed for maintenance-free operation, these motors dissipate heat effectively through their surface, maintaining consistent performance during continuous operation. The SIMOTICS S-1FK7 range also ensures high overload capability and reliability under fluctuating mechanical loads.

Design and Application

The 1FK7044-4CF71-1CH0 features a rugged frame design for IMB 5 mounting (IM V1, IM V3) with flange 1, supporting easy integration into existing systems. Its naturally cooled body and compact structure save space in cabinets and machine housings, making it ideal for modern, high-speed automation setups. Typical applications include machine tools, robots, packaging machines, textile systems, and printing equipment. With fast response characteristics, minimal commissioning effort, and compatibility with advanced Siemens drives, this motor ensures precise torque output and dependable performance for both light and heavy-duty motion sequences.
