1FK7044-4CF71-1UG1-ZJ03 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CF71-1UG1-ZJ03 represents a new generation of high-performance synchronous motors engineered for precision and reliability in demanding automation environments. With a power rating of 1.2 kW, nominal torque of 4.5 Nm, and a rated speed of 3000 rpm, this naturally cooled motor provides excellent efficiency and energy balance in compact spaces. It features a rotatable power connector and a multi-pole resolver with a DRIVE-CLiQ interface for seamless integration with the SINAMICS S120/S220 drive systems. The unit also includes an ALPHA SP+ SP 075S-MF1 planetary gearbox (ratio 5:1) for superior torque transmission and consistent performance across a wide range of applications.

Overview

The SIMOTICS S 1FK7 series is renowned for its combination of compact design and dynamic responsiveness. These permanent-magnet synchronous motors deliver high power density and are suitable for universal use across numerous industrial sectors. They can be precisely tailored to specific applications through a wide selection of gearboxes, encoder systems, and mounting options. Each motor in the series is optimized for operation without external cooling, relying on efficient surface heat dissipation for stable thermal management. The integrated encoder options ensure accurate speed and position control, allowing reliable performance even in fast-changing production processes.

Design and Benefits

Built to achieve the perfect balance between size and capability, the SIMOTICS S 1FK7044-4CF71-1UG1-ZJ03 motor offers flexible installation with a flange-mounted IMB 5 configuration and IP65 protection for durability in harsh conditions. The design supports both High Dynamic and High Inertia variants, enabling precise motion control whether speed or torque is prioritized. This motor minimizes commissioning effort and maintains outstanding stability under variable load conditions. Its integration flexibility, low noise, and smooth torque curve make it ideal for advanced industrial systems such as robotics, packaging, machining, and printing equipment.
