Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About
The Siemens 1FT7084-5AF71-1KB2 is a SIMOTICS S-1FT7 synchronous servo motor designed for high-performance motion control, CNC machine tools, and industrial automation applications. It is a permanent-magnet synchronous motor with natural cooling, delivering an optimum rated power of 4.5 kW at a rated speed of 3,000 RPM and rated torque of 14.5 Nm. The motor has 10 poles, a maximum mechanically permissible speed of 8,000 RPM, and a maximum inverter speed of 5,000 RPM. Its maximum torque is 81 Nm, with a maximum current of 55 A. The motor has a rotor moment of inertia of 60.40 kgcm and a net weight of approximately 25.1 kg. It incorporates a permanent-magnet holding brake with 48 Nm holding torque and 24 V DC supply. The motor features IP67 protection, IM B5 mounting, a fitted-key shaft, Pt1000 temperature monitoring, and an AS24DQI absolute single-turn 24-bit encoder with Drive-CLiQ interface. The turnable electrical connector makes it suitable for flexible machine installation.
