1FK7042-2AF71-1PB0 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with model number 1FK7042-2AF71-1PB0 represents exceptional reliability and precision in motion control applications. Designed for demanding industrial automation systems, this compact permanent-magnet motor delivers continuous performance with a rated power of 0.82 kW, torque of 3 Nm, and speed of up to 3000 rpm. Its naturally cooled construction ensures efficient heat dissipation through the motor surface, making it ideal for continuous operation under challenging conditions. The durable IMB 5 (IM V1, IM V3) flange design with a rotatable power connector and two-pole resolver provides flexibility for multiple installation scenarios.

Overview

The SIMOTICS S-1FK7 series combines compact size, high torque density, and consistent accuracy to meet modern automation requirements. Each motor is built to integrate seamlessly with the SINAMICS S120 or S220 drive system, creating a robust, high-functionality solution for dynamic motion control. Integrated encoder systems enable precise feedback for speed and position regulation, ensuring optimized control in every operation. The SIMOTICS S-1FK7 motor family features various frame sizes and torque classes, allowing easy adaptation to machine designs and mechanical interfaces.

Design and Benefits

The 1FK7042-2AF71-1PB0 motor is engineered with a naturally cooled housing, IP64 protection, and a holding brake for enhanced safety. It features a shaft with a feather key and tolerance N for reliable mechanical coupling. With its lightweight yet rugged construction, the motor provides low-maintenance operation and excellent vibration resistance. The SIMOTICS S Compact line emphasizes space-saving installation, while the High Dynamic variant offers exceptional responsiveness due to a low rotor moment of inertia. Meanwhile, High Inertia models deliver smooth control under varying loads, reducing tuning time during commissioning.

Typical applications include machine tools, robots, packaging equipment, printing machines, and precision handling systems. This high-performance synchronous motor delivers accurate positioning, stable speed control, and minimal downtime — a perfect match for industries demanding long-term reliability and efficiency.
