1FK7042-2AF71-1CH1-ZJ13 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor with ALPHA SP+ Gearbox Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with model number 1FK7042-2AF71-1CH1-ZJ13 is an advanced permanent-magnet synchronous motor built to deliver reliability, efficiency, and precision across industrial automation applications. Designed with natural cooling and a rugged IP65 protection class, this unit ensures dependable operation even in challenging environments. With a nominal torque of 3 Nm, a rated speed of 3000 rpm, and a power output of 0.82 kW, it provides stable performance for continuous duty operations. The integrated 24-bit + 12-bit multiturn absolute encoder (AM24DQI) with DRIVE-CLiQ interface guarantees superior feedback accuracy, supporting dynamic and responsive motion control.

Overview

The SIMOTICS S-1FK7 series represents the next generation of compact synchronous motors engineered for high power density and energy efficiency. These motors are perfectly matched with SINAMICS S120/S220 drive systems, forming a complete, high-functionality motion platform. The flexible configuration options — including multiple frame sizes, encoder systems, and integrated gearboxes — enable precise adaptation to diverse industrial requirements. Heat dissipation occurs naturally through the motor surface, removing the need for external cooling systems and minimizing maintenance demands.

Design and Application

The 1FK7042-2AF71-1CH1-ZJ13 variant is equipped with an ALPHA SP+ SP 075S-MF2 planetary gearbox featuring a two-stage ratio (i = 20) and feather-key connection for robust torque transmission. Its high overload capacity and exceptional motion precision make it ideal for demanding automation processes. This motor is widely used in machine tools, robotic systems, packaging lines, and precision assembly machinery. It also finds applications in wood, glass, ceramics, and textile processing systems, where accuracy, efficiency, and compactness are essential.

By integrating the latest motor and encoder technologies, the SIMOTICS S-1FK7 family ensures fast response times, minimal inertia, and easy commissioning. Users benefit from space-saving design, long-term durability, and seamless compatibility with modern servo drive architectures — offering reliable performance and reduced downtime in industrial environments.
