1FK7042-3BK71-1QG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7042-3BK71-1QG1 belongs to the renowned SIMOTICS S-1FK7 series of permanent-magnet synchronous motors, engineered for precision, efficiency, and endurance in advanced industrial automation. With a rated power of 0.94 kW, a voltage of 600 V DC, and a nominal torque of 3 Nm at 6000 rpm, this high-performance unit provides consistent output for high-speed and high-accuracy motion control systems. Designed with a naturally cooled construction (IMB 5/IM V1/IM V3) and a rotatable power connector, it ensures flexibility and reliability in diverse installation environments.

The motor integrates an absolute single-turn 20-bit encoder (AS20DQI) with DRIVE-CLiQ interface, delivering precise feedback for position and velocity control. Its smooth shaft and IP65-rated enclosure make it suitable for demanding applications where dust and water resistance are essential. Without a holding brake and with tolerance N, the motor achieves stable performance and minimal maintenance over long operating periods.

Overview

SIMOTICS S-1FK7 motors are compact synchronous servo units that combine high torque density with low moment of inertia. Available with various encoder systems and mechanical configurations, the 1FK7 series can be easily customized to meet the evolving requirements of modern automation. When paired with SINAMICS S120 or S220 drive systems, they form a highly responsive and efficient drive solution offering dynamic motion control and energy-saving operation.

Design and Performance

The 1FK7042-3BK71-1QG1 motor features a robust design optimized for natural convection cooling. Its compact housing allows space-saving installation while ensuring mechanical strength under continuous duty.
