1FK7042-2AF71-1UB2 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with the product code 1FK7042-2AF71-1UB2 is a precision-engineered servo solution developed for demanding automation environments. Delivering a rated power of 0.82 kW and torque of 3 Nm at 3000 rpm, this motor is designed for reliability, precision, and long-term operational stability. With a naturally cooled compact construction, flange IMB 5 (IM V1, IM V3), and IP65 / IP67 protection, it ensures robust performance even under challenging industrial conditions. The multi-pole resolver equipped with a DRIVE-CLiQ interface allows precise feedback control, guaranteeing exceptional accuracy in motion and positioning.

Overview

The SIMOTICS S-1FK7 motor series from SIEMENS represents the latest generation of compact permanent-magnet synchronous motors. Designed to meet evolving machine-building standards, these motors combine versatility and performance within a minimal footprint. Each motor integrates advanced encoder systems and can be seamlessly paired with SINAMICS S120 or S220 drive systems to form a highly dynamic and energy-efficient drive package. This integration supports smooth speed regulation, precise torque delivery, and enhanced overall productivity.

Design and Benefits

SIMOTICS S-1FK7 motors are engineered for easy installation and maintenance-free operation. Heat dissipation occurs efficiently through the motor’s external surface, eliminating the need for auxiliary cooling systems. Depending on model selection, users may choose from compact, high-dynamic, or high-inertia variants to suit specific mechanical requirements. The compact version provides a space-saving footprint ideal for universal machine applications, while the high-dynamic design offers an ultra-responsive rotor with minimal inertia for rapid acceleration and deceleration. The high-inertia configuration ensures smooth control for variable load conditions and reduces commissioning time.

Typical applications include machine tools, industrial robots, packaging and textile machinery, as well as equipment for wood, glass, and stone processing. Each motor in the 1FK7 range is built for precision, durability, and continuous operation in automated production lines where consistency is critical.
