1FK7043-4CK71-1RA1 SIEMENS Exclusive High-Performance Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CK71-1RA1 is a high-performance synchronous motor from the SIMOTICS S-1FK7 series, built to deliver precise, efficient, and reliable motion control across a wide range of automation systems. With a nominal power output of 1.3 kW and rated torque of 3.5 Nm, this model achieves speeds up to 6000 rpm under a 600 V DC supply. Its naturally cooled design ensures dependable operation with minimal maintenance, while the IMB 5 (IM V1, IM V3) flange mounting configuration allows for easy installation in both vertical and horizontal setups. The rotatable power connector and 20-bit + 12-bit multi-turn absolute encoder (AM20DQI) provide seamless integration with modern drive systems via DRIVE-CLiQ communication.

Overview

The SIMOTICS S-1FK7 motor family represents the latest generation of compact permanent-magnet synchronous motors. Designed for flexibility, these motors can be tailored through numerous options including encoders, gearboxes, and mounting variants. The 1FK7 lineup works perfectly with SINAMICS S120 and S220 drive systems to form a powerful, intelligent motion solution offering smooth control and exceptional accuracy. The integrated feedback system ensures precise speed and position regulation, supporting demanding automation and manufacturing tasks. Engineered for convection cooling, the motor effectively dissipates heat through its housing, enhancing performance stability during extended operation.
