The SIEMENS 1FK7043-4CH71-1CA2 SIMOTICS S synchronous motor delivers precise motion control with 1.2 kW power, 3.5 Nm torque, and a high-resolution DRIVE-CLiQ encoder, built for advanced automation systems.
The SIEMENS SIMOTICS S 1FK7043-4CH71-1CA2 represents a new generation of compact synchronous servo motors designed for precision, durability, and efficiency in advanced automation systems. Delivering a rated power of 1.2 kW and a nominal torque of 3.5 Nm, this motor provides excellent torque density in a naturally cooled housing. With a nominal speed of 4500 rpm and IP65/IP67 protection, it ensures consistent performance even in harsh industrial conditions. The model features a 24-bit + 12-bit multiturn absolute encoder with DRIVE-CLiQ interface for accurate feedback and positioning, as well as a rotatable power connector for flexible installation. Its compact frame size (IMB 5, IM V1, IM V3) allows for space-saving integration into modern machine designs.
The SIMOTICS S-1FK7 motor family is engineered to combine high dynamics with exceptional precision. Built using permanent-magnet technology, these motors are optimized for integration with SINAMICS S120/S220 drive systems, forming a complete motion-control solution with seamless communication and reliable performance. The 1FK7043-4CH71-1CA2 model belongs to the High Dynamic (HD) range, ensuring rapid acceleration and fast response times—ideal for demanding servo applications where speed and control accuracy are critical. Heat dissipation through the external surface allows the unit to operate without additional cooling, maintaining optimal temperature stability and long-term reliability.
