Description
Product Description
The Siemens 1FT7082-5AH7X-1XXX is a SIMOTICS S-1FT7 permanent magnet synchronous servo motor engineered for high-speed, high-precision motion control in demanding industrial automation environments. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems via the DRIVE-CLiQ interface, this naturally cooled motor delivers exceptional dynamic performance, excellent positioning accuracy, and reliable continuous-duty operation. It is ideal for CNC machine tools, industrial robotics, packaging machinery, semiconductor manufacturing, printing systems, and advanced material handling applications.
Operating at a rated speed of 4,500 RPM, the 1FT7082-5AH7X-1XXX provides 3.77 kW rated output power, 8.0 Nm rated torque, and 13.0 Nm stall torque (100 K). The motor can generate up to 52 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, ensuring rapid acceleration, high overload capability, and precise servo control. The permanent magnet rotor design offers high torque density, low inertia, and excellent energy efficiency.
The 1FT7082-5AH7X-1XXX product family is available in multiple MLFB configurations with various encoder technologies, shaft designs (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and protection classes. All variants feature natural cooling, IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication. The exact configuration is determined by the complete Siemens MLFB ordering code.
