1FK7043-4CH71-1BA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CH71-1BA1 SIMOTICS S synchronous motor is an advanced permanent-magnet motor designed for high-performance industrial applications. Delivering 1.2 kW power at a rated speed of 4500 rpm and a nominal torque of 3.5 Nm, this compact motor offers excellent efficiency and reliability. Its naturally cooled design with IP65 protection ensures durability even in challenging environments. The motor includes a rotatable power connector and a 24-bit singleturn absolute encoder with DRIVE-CLiQ interface, providing precise speed and position control. The shaft comes with a fitted key and tolerance N for seamless integration into machine systems, and the motor is delivered without a holding brake for flexible operational configurations.

Overview

The SIMOTICS S-1FK7 series represents a compact and versatile line of synchronous motors that can be adapted to a wide range of industrial requirements. With options for encoders, gearboxes, and expanded product variations, these motors meet the demands of modern machine generations while maintaining high efficiency and dynamic performance. The integrated encoder systems can be selected to suit specific applications, making them ideal for high-precision operations.

Benefits

• Space-saving installation: The compact form factor and high power density make it ideal for constrained mechanical setups.
• Universal applications: Suitable for robots, handling systems, packaging machines, machine tools, printing, and auxiliary axes.
• High dynamic performance: Low rotor inertia ensures rapid response for precise motion control.
• Robust operation: Motors with high inertia maintain stable closed-loop control even under varying load conditions.
• Minimal commissioning: Optimized design reduces the effort for system integration and disturbance compensation.

Applications

The 1FK7043-4CH71-1BA1 motor is engineered for use across diverse sectors including machine tools, robotics, packaging, plastics, textiles, and printing industries. Its robust design ensures high reliability for continuous operation, while the precise encoder integration supports advanced motion control systems such as SINAMICS S120/S220 drives. Heat dissipation through the motor surface allows operation without external cooling, maximizing operational efficiency and lifespan.
