1FK7043-4CF21-1RG0 SIEMENS Exclusive High-Performance Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7-HD 1FK7043-4CF21-1RG0 is a compact, high-precision synchronous motor engineered for demanding industrial applications. Delivering 0.94 kW of nominal power and a rated torque of 3.3 Nm at 3000 rpm, this naturally cooled motor operates without external cooling and dissipates heat efficiently through its surface. Its robust design features IP64 protection, a rotatable power connector, and an integrated 20-bit absolute encoder with 12-bit multiturn for accurate position and speed control. The motor’s plain shaft (tolerance N) ensures compatibility with a variety of mechanical configurations, while the Drive-CLiQ interface enhances system integration.

Overview

The SIMOTICS S-1FK7 series is renowned for its compact size and adaptability. These permanent-magnet synchronous motors are compatible with a wide range of gearboxes and encoders, allowing precise tailoring to specific machine requirements. When combined with the SINAMICS S120 or S220 drive systems, they form a high-performance drive solution with extensive functionality for modern automation setups. The integrated encoder system supports both speed and position regulation, providing reliable closed-loop control in complex operations.

Key Benefits
