1FK7042-2AF71-1FG2 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor with model 1FK7042-2AF71-1FG2 represents advanced servo technology for modern automation systems. Designed to deliver precise performance, this compact permanent-magnet motor provides a rated power of 0.82 kW and a torque of 3 Nm at 3000 rpm. Its naturally cooled design ensures efficient heat dissipation, extending operational reliability while maintaining silent operation. The 1FK7042-2AF71-1FG2 is built for demanding industrial tasks where consistency, compactness, and durability are essential.

With a Drive-CLiQ interface and an integrated AM22DQ multiturn absolute encoder (22-bit + 12-bit), this motor offers precise position feedback for closed-loop control. The plain shaft design with tolerance class N provides smooth mechanical performance, while the IP65/IP67 protection levels safeguard the motor against dust and moisture. Its rotatable power connector and flexible mounting style (IMB 5 / IM V1 / IM V3) make installation effortless across various machine configurations.

Overview

The SIMOTICS S-1FK7 family consists of compact, high-torque synchronous motors that combine exceptional dynamics with reliability. Thanks to modular options in encoders and gearboxes, the series adapts to a wide range of motion-control applications. When paired with SINAMICS S120 or S220 drive systems, it creates a high-precision servo solution offering outstanding positioning accuracy and performance consistency. These motors are engineered for self-cooling through their housing surface, ensuring reduced maintenance requirements and longer operational life.

Benefits and Applications

The 1FK7042-2AF71-1FG2 compact motor allows space-saving installation due to its high power density. It delivers rapid acceleration and deceleration through a low rotor moment of inertia, ensuring smooth and dynamic response. The rugged construction ensures stable control even under fluctuating load conditions. Typical fields of application include machine tools, robotics, packaging, printing, plastic forming, woodworking, and textile production. Each motor provides the reliability and energy efficiency that industries expect from the SIEMENS SIMOTICS range.
