Description
Product Description
The Siemens 1FT7034-5AK7X-1XXX is a compact SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-speed, high-precision motion control applications. Engineered for seamless integration with Siemens SINAMICS S120 servo drive systems via the DRIVE-CLiQ interface, this naturally cooled servo motor delivers excellent positioning accuracy, rapid acceleration, and reliable continuous-duty performance. It is ideally suited for CNC machinery, robotics, packaging equipment, semiconductor manufacturing, electronics assembly, printing systems, and other advanced automation applications.
Operating at a rated speed of 6,000 RPM, the 1FT7034-5AK7X-1XXX provides 0.88 kW optimum output power, 1.4 Nm rated torque, and 2.0 Nm stall torque (100 K). The motor is capable of delivering up to 8.0 Nm maximum torque while supporting a maximum mechanical speed of 10,000 RPM, making it ideal for applications requiring extremely fast response, smooth operation, and high positional accuracy. Its permanent magnet rotor design ensures high efficiency, low rotor inertia, and outstanding dynamic performance.
The 1FT7034-5AK7X-1XXX product family includes numerous MLFB variants with different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, temperature sensor options (KTY or Pt1000), vibration grades, and IP protection ratings. All variants feature natural cooling, IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication. The final configuration is determined by the complete Siemens MLFB ordering code.
