The SIEMENS SIMOTICS S 1FK7043-4CH71-1RH1-ZJ03 is a high-performance synchronous motor featuring 1.2 kW output, DRIVE-CLiQ encoder, holding brake, and planetary gear for precise, reliable industrial automation.
The SIEMENS SIMOTICS S 1FK7043-4CH71-1RH1-ZJ03 is a precision-engineered synchronous motor designed for applications that demand exceptional performance, accuracy, and efficiency. Delivering a nominal power of 1.2 kW at 600 V DC and a rated torque of 3.5 Nm, this model achieves a rated speed of 4500 rpm with natural cooling for stable operation.
Built in a robust IMB5 construction with a rotatable power connector and integrated absolute encoder 20-bit + 12-bit multiturn with DRIVE-CLiQ interface (AM20DQI), it ensures reliable feedback and seamless communication with compatible SIEMENS drive systems. The motor features a plain shaft with N tolerance, an IP65 protection rating, and an integrated holding brake for enhanced operational safety. This specific variant is equipped with the ALPHA SP+ SP 075S-MF1 planetary gearing (1 stage, i=5, with feather key) for precise torque transmission and high mechanical stability.
The SIMOTICS S-1FK7 motor series represents SIEMENS’ advanced generation of compact permanent-magnet synchronous motors. Engineered for outstanding versatility, these motors offer a wide range of options including encoders, cooling variants, and gear units to match diverse industrial needs. When paired with SINAMICS S120 or S220 drive systems, they create a powerful, high-functionality motion control solution capable of smooth speed and position regulation. Designed for operation without external cooling, these motors efficiently dissipate heat through their housing surface, maintaining performance consistency under demanding conditions.
The SIMOTICS S-1FK7 family provides exceptional flexibility with Compact, High Dynamic, and High Inertia variants to suit specific motion requirements. The compact configuration supports space-saving installation with high power density, while the low rotor moment of inertia enables fast dynamic response. High Inertia versions deliver robust control characteristics for fluctuating load conditions. These features make the 1FK7043-4CH71-1RH1-ZJ03 ideal for use in machine tools, robotics, automation systems, packaging, printing, and various material processing machines, ensuring smooth, precise, and energy-efficient performance.
