Description
Product Description
The Siemens 1FT7068-5AF7X-1XXX is a member of the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, designed for high-performance industrial motion control applications that require exceptional precision, high torque density, and outstanding dynamic response. Engineered for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor is ideal for CNC machine tools, industrial robotics, packaging equipment, semiconductor manufacturing, material handling systems, printing machinery, and automated production lines.
Operating at a rated speed of 3,000 RPM, the 1FT7068-5AF7X-1XXX delivers 3.42 kW rated output power, 10.9 Nm rated torque, and 15.0 Nm stall torque (100 K). The motor is capable of producing up to 63 Nm maximum torque while supporting maximum mechanical speeds of 9,000 RPM, ensuring rapid acceleration, excellent overload capability, and highly accurate motion control. Its permanent magnet rotor design provides high efficiency, low rotor inertia, and superior servo performance.
The 1FT7068-5AF7X-1XXX product 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 exact configuration is determined by the complete Siemens MLFB order number.
