Description
Product Description
The Siemens 1FT7086-5AH7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial automation applications requiring high-speed operation, precise positioning, and excellent dynamic response. Optimized for use with Siemens SINAMICS S120 servo drive systems through the DRIVE-CLiQ interface, this naturally cooled motor delivers outstanding efficiency, high torque density, and reliable long-term performance for CNC machine tools, robotics, packaging machinery, semiconductor equipment, printing systems, and advanced material handling applications.
Operating at a rated speed of 4,500 RPM, the 1FT7086-5AH7X-1XXX delivers 4.71 kW optimum output power, 10 Nm rated torque (100 K), and 28 Nm stall torque (100 K). The motor is capable of producing up to 120 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, providing excellent overload capability, rapid acceleration, and highly accurate motion control. Its permanent magnet rotor ensures low inertia, smooth operation, and superior energy efficiency.
The 1FT7086-5AH7X-1XXX family includes 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, integrated temperature monitoring, and DRIVE-CLiQ communication for simplified commissioning and diagnostics. The exact motor configuration depends on the complete Siemens MLFB ordering code.
