Description
Product Description
The Siemens 1FT7084-5SH7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial automation and precision motion control applications. Featuring forced ventilation cooling, this servo motor delivers exceptional torque density, high-speed operation, and outstanding dynamic response while integrating seamlessly with Siemens SINAMICS S120 drive systems via the DRIVE-CLiQ interface. It is ideal for CNC machine tools, industrial robotics, packaging machinery, printing equipment, rotary tables, and automated manufacturing systems.
Operating at a rated speed of 4,500 RPM, the 1FT7084-5SH7X-1XXX provides an optimum output power of 9.90 kW, 21 Nm rated torque (100 K), and 27 Nm stall torque (100 K). The motor is capable of delivering up to 81 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, making it suitable for high-speed, high-precision applications requiring continuous-duty reliability.
The 1FT7084-5SH7X-1XXX product family is available in numerous MLFB configurations with multiple encoder options, shaft versions (plain shaft or fitted key), optional permanent-magnet holding brakes, connector orientations, vibration grades, and IP protection classes. All variants feature IM B5 flange mounting, integrated motor temperature monitoring, and DRIVE-CLiQ communication for simplified commissioning and advanced diagnostics.
