1FK7042-2AF71-1FA1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with part number 1FK7042-2AF71-1FA1 is a high-efficiency, compact motor engineered for precise motion control in industrial automation. Delivering a nominal power of 0.82 kW and a rated torque of 3 Nm, this advanced model is designed for natural cooling and ensures excellent thermal stability during continuous operation. With a rated speed of 3000 rpm, the motor offers smooth acceleration, stable performance, and consistent torque output across varying loads, making it ideal for demanding production environments.

The motor features a Drive-CLiQ interface with an AM22DQ absolute encoder providing 22-bit + 12-bit multiturn precision for accurate positioning and feedback control. Its shaft with fitted key, IP65 degree of protection, and robust IMB 5 frame design allow reliable performance in challenging industrial conditions. The rotatable power connector offers flexible installation, while its maintenance-free design ensures long-term reliability with minimal downtime.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ premium line of permanent-magnet synchronous motors, developed for applications requiring compact size, high power density, and superior control accuracy. Each motor is optimized for integration with the SINAMICS S120/S220 drive systems, forming a powerful, modular automation solution. The combination ensures dynamic motion performance, quick start-up, and seamless communication through the integrated encoder system.

These motors are naturally cooled via their surface structure, which efficiently dissipates heat without additional equipment. Their high overload capacity and optimized rotor design enhance response time, making them particularly suited for fast, precise, and repeatable motion sequences.

Benefits

• Compact and space-saving design with exceptional power-to-size ratio.
• High dynamic response through low rotor inertia.
• Reliable closed-loop control for stable operation under varying loads.
• Flexible encoder and gearbox options for tailored system integration.
• Engineered for reduced maintenance and extended service life.

Applications

This motor series is widely used in machine tools, robotics, packaging systems, and processing equipment for materials such as wood, glass, ceramics, plastics, and textiles. It also performs exceptionally in printing machinery and auxiliary axis configurations, where precision and reliability are essential.
