Siemens SIMOTICS S-1FK7 High Dynamic Servo Motor About

The Siemens SIMOTICS S 1FK7086-4SF71-1RB1 is a high-dynamic, three-phase permanent-magnet synchronous servo motor from the SIMOTICS S-1FK7 High Dynamic series. The exact Siemens datasheet specifies 7.5 kW optimum power, 3,000 RPM rated speed, and 24 Nm rated torque at 100 K, with 38 Nm static torque at 100 K. It uses forced ventilation and supports IM B5, IM V1 and IM V3 mounting. The motor is fitted with an AM20DQI absolute encoder, offering 20-bit position resolution (1,048,576 counts) plus 12-bit multiturn capability over 4,096 revolutions, with DRIVE-CLiQ-compatible feedback. It has a feather-key shaft, permanent-magnet holding brake, and IP54/65 protection. The motor weighs approximately 30 kg and has an 80 mm shaft height. It is designed for demanding CNC, machine-tool, robotics, production and industrial automation applications requiring high torque and precise dynamic motion control.
