1FK7043-4CH71-1QA2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CH71-1QA2 is a high-precision synchronous motor engineered for industrial automation systems requiring exceptional reliability, power efficiency, and control accuracy. Delivering a rated power of 1.2 kW and torque of 3.5 Nm at 4500 rpm, this motor provides stable performance across demanding motion control environments. With a durable IP65/IP67 degree of protection, it withstands dust, vibration, and moisture, ensuring long service life even in harsh industrial conditions. Its rotatable power connector and naturally cooled design allow flexible integration into multiple machine configurations, making it ideal for diverse mechanical and automation setups.

Equipped with an absolute single-turn 20-bit encoder with DRIVE-CLiQ interface (AS20DQI), the motor offers precise feedback for accurate positioning and dynamic control. The shaft with fitted key ensures secure torque transmission, while the absence of a holding brake minimizes maintenance requirements. Designed to operate without external cooling, the SIMOTICS S motor dissipates heat efficiently through its housing, supporting consistent operation over extended cycles.

Overview

The SIMOTICS S-1FK7 series represents a new generation of compact, permanent-magnet synchronous motors built for performance, flexibility, and efficiency. When combined with the SINAMICS S120 or S220 drive systems, these motors deliver high functionality and adaptability for complex motion control tasks. Their integrated encoder systems can be tailored to various precision levels, ensuring smooth speed and position control for multiple industrial applications.
