The Siemens SIMOTICS S 1FK7042-5AF71-1PA0 is a three-phase permanent-magnet synchronous servo motor from the SIMOTICS S-1FK7 Compact series. It provides 0.8 kW optimum power at 3,000 RPM, with 2.6 Nm rated torque and 3.0 Nm static torque. The motor uses natural cooling and is designed for IM B5, IM V1 and IM V3 mounting. This configuration is equipped with a 2-pole resolver (P=1) with DRIVE-CLiQ interface, providing reliable position feedback for precision motion-control systems. It has a fitted-key shaft with tolerance N, no holding brake, and IP64 protection. The power and signal connector can be rotated through 270, allowing flexible installation. Siemens specifies a maximum mechanical speed of 9,000 RPM, maximum inverter speed of 6,500 RPM, and maximum torque of 10.5 Nm. The motor is suitable for CNC machines, robotics, machine tools, packaging equipment, automated assembly, and industrial automation applications.
