Description
Product Description
The Siemens 1FT7066-5AF7X-1XXX belongs to the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for demanding industrial motion control applications requiring high torque density, exceptional positioning accuracy, and outstanding dynamic performance. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor is ideal for CNC machine tools, industrial robotics, packaging machinery, printing equipment, semiconductor manufacturing, material handling systems, and automated production lines.
Operating at a rated speed of 3,000 RPM, the 1FT7066-5AF7X-1XXX delivers 2.92 kW rated output power, 9.3 Nm rated torque, and 12.0 Nm stall torque (100 K). The motor can produce up to 49 Nm maximum torque while supporting maximum mechanical speeds of 9,000 RPM, providing rapid acceleration, excellent overload capability, and highly accurate motion control. The permanent magnet rotor ensures high efficiency, low rotor inertia, and superior servo performance.
The 1FT7066-5AF7X-1XXX family is available in numerous MLFB variants with different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and protection classes. All variants feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, and integrated motor temperature monitoring. The final configuration is determined by the complete Siemens MLFB order number.
