1FK7042-2AF71-1BB2 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor, model 1FK7042-2AF71-1BB2, represents the next generation of precision motion control in modern automation. Delivering 0.82 kW nominal power with a torque of 3 Nm and a rated speed of 3000 r/min, this compact synchronous servo motor ensures maximum efficiency, reliability, and versatility. Designed for natural cooling, the motor features a robust IP65-rated housing and a precisely machined flange connection (IM B5 / IM V1 / IM V3) for stable installation in demanding environments.

Equipped with a DRIVE-CLiQ single-turn 24-bit encoder (AS24DQI) and an integrated holding brake, the motor allows highly accurate feedback and consistent positioning performance. Its rotatable power connector simplifies installation and supports flexible cable routing, making it ideal for space-restricted machines. With protection ratings up to IP67 on the drive-end flange, this motor provides excellent resistance to dust and moisture.

Overview

The SIMOTICS S-1FK7 series is a family of compact permanent-magnet synchronous motors engineered for maximum flexibility. Combined with SINAMICS S120 or S220 drive systems, these motors deliver seamless performance in dynamic motion applications. Their modular range, including various shaft designs, encoder types, and optional gearboxes, enables tailored solutions for automation across multiple industries.

The series offers high power density within minimal installation space, making it ideal for compact machine layouts. Thanks to the efficient surface cooling system, the motors operate reliably without external fans. The rugged mechanical design ensures extended service life and reduced maintenance requirements, even in continuous-operation conditions.
