1FK7042-2AK71-1BG2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1BG2 is a precision-engineered synchronous motor designed for high-performance industrial automation. Delivering a continuous rated power of 0.94 kW and torque of 3 Nm at 6000 rpm, it provides reliable efficiency and superior motion accuracy. With a compact IMB 5 construction and a rotatable power connector, this unit ensures installation flexibility even in tight-space environments. Its naturally cooled design supports consistent operation without the need for external cooling, making it ideal for long-term continuous-duty applications.

Equipped with a single-turn 24-bit absolute encoder featuring Drive-CLiQ interface, the 1FK7042-2AK71-1BG2 offers precise position feedback for superior control and smooth performance. The IP65-rated housing (IP67 at DE flange) enhances protection against dust and moisture, guaranteeing reliable service life even under demanding production conditions. Designed without a holding brake and featuring a smooth shaft with tolerance N, this SIEMENS motor combines durability, accuracy, and low maintenance requirements in one robust solution.

Overview

The SIMOTICS S-1FK7 series represents a new generation of compact, permanent-magnet synchronous motors built for modern machine concepts. These motors can be configured with a variety of encoders, shaft designs, and cooling methods to suit different mechanical requirements. When integrated with SINAMICS S120 or S220 drive systems, they form a powerful, energy-efficient motion control package capable of precise speed and torque regulation.

• High power density for space-saving installation
• Flexible adaptation through multiple design variants
• Integrated encoder options for accurate motion control
• Excellent overload capacity for dynamic operation

Benefits

The SIMOTICS S-1FK7 Compact motors provide universal usability and impressive performance in confined spaces. The High Dynamic variants deliver exceptional acceleration due to a low rotor moment of inertia, while the High Inertia models ensure smooth, stable motion in processes with fluctuating loads. Together, these variants offer unmatched versatility across industries such as machine tools, robotics, and packaging.

• Outstanding torque stability and efficiency
• Reliable closed-loop control even with high load variations
• Minimal commissioning time for faster system setup

Applications: machine tools, robotics, handling systems, printing, wood and stone processing, textile, and packaging machinery.
