1FK7042-3BK71-1BH2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S Synchronous Motor 1FK7042-3BK71-1BH2 is a high-efficiency servo motor engineered for modern automation systems where precision, performance, and durability are essential. Delivering a rated power of 0.94 kW with a torque of 3 Nm, it operates at a nominal speed of 6000 rpm and a DC link voltage of 600 V. Its naturally cooled construction and versatile IMB 5 mounting configuration ensure reliable performance in diverse industrial setups while minimizing maintenance requirements.

This SIMOTICS S 1FK7 High Inertia motor features a smooth shaft, IP65 protection, and an integrated holding brake for secure operation. The rotatable power connector enhances installation flexibility, and the built-in absolute single-turn 24-bit encoder with DRIVE-CLiQ interface (AS24DQI) provides precise feedback for superior motion control. Designed to operate seamlessly with SINAMICS S120 and S220 drive systems, this unit achieves excellent dynamic performance and long-term reliability in demanding environments.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ advanced generation of permanent-magnet synchronous motors. Their compact design and high power density make them suitable for applications requiring minimal space and maximum torque. The modular structure, combined with a wide choice of encoders and gear options, allows complete customization for automation and motion-control systems.

• Operation without external cooling — heat dissipated efficiently through the motor surface
• High overload capacity for short-term torque peaks
• Supports precise speed and position control through integrated encoders
• Perfectly harmonized with SINAMICS drive systems for coordinated operation

Design and Benefits

The robust aluminum housing ensures mechanical strength and resistance to industrial conditions. Compact construction allows space-saving integration into machine tools, packaging equipment, and robotics. The 1FK7042-3BK71-1BH2 motor provides reliable motion even under varying loads, with minimal commissioning time due to its stable closed-loop control properties.

• Compact dimensions for flexible installation
• Low moment of inertia enabling smooth acceleration and deceleration
• Consistent torque and high accuracy in repetitive applications
• Designed for continuous operation in harsh environments

Applications: CNC machines, robotic arms, handling systems, packaging lines, printing machines, and textile automation.
