Description
Product Description
The Siemens 1FT7086-5AC7X-1XXX is part of the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for demanding motion control applications requiring high precision, rapid acceleration, and exceptional reliability. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this servo motor family is ideal for CNC machine tools, industrial robotics, packaging machinery, material handling systems, semiconductor manufacturing, printing equipment, and automated production lines. The compact design, high power density, and excellent dynamic characteristics make it suitable for continuous industrial operation.
Operating at a rated speed of 2,000 RPM, the 1FT7086-5AC7X-1XXX series delivers 4.71 kW rated output power, 22.5 Nm rated torque, and 28 Nm stall torque (100 K). The motor provides up to 120 Nm maximum torque and supports maximum mechanical speeds of 8,000 RPM, ensuring excellent overload capability, fast response, and precise positioning. The permanent magnet synchronous design offers high efficiency, low rotor inertia, and smooth speed regulation for advanced servo applications.
The 1FT7086-5AC7X-1XXX family is available in numerous MLFB variants with different encoder systems, shaft configurations (plain shaft or keyed shaft), optional holding brakes, connector orientations, and balancing grades. All variants feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, integrated motor temperature monitoring, rotatable power connectors, and IP65 protection (configuration dependent). The exact electrical and mechanical configuration is determined by the complete Siemens MLFB ordering code.
