1FK7043-4CH71-1RG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CH71-1RG1 is a premium-grade synchronous motor engineered for superior precision, energy efficiency, and long-term reliability in advanced automation systems. With a rated power of 1.2 kW and torque of 3.5 Nm (100K), this motor delivers outstanding performance at up to 4500 rpm. Designed for natural cooling, it operates within a compact frame size IMB 5 (IM V1, IM V3) and features a flange-mounted configuration for space-efficient installation. The rotatable power connector and absolute encoder 20-bit + 12-bit multiturn with DRIVE-CLiQ interface (AM20DQI) ensure accurate position feedback and high integration flexibility. With a plain shaft, tolerance N, and IP65 protection, this model is robust enough for challenging industrial environments, while maintaining smooth operation without a holding brake.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ latest generation of compact, high-efficiency synchronous motors. Designed for dynamic performance, these motors combine cutting-edge permanent magnet technology with precision control to achieve exceptional accuracy and responsiveness. They can be seamlessly integrated with SINAMICS S120 or S220 drive systems to form a high-performance motion control solution suitable for complex automation setups. Each unit incorporates an advanced encoder system for optimized speed and position regulation. The 1FK7 family also offers excellent heat dissipation through natural convection, ensuring high reliability and durability even in continuous operation.
