Description
Product Description
The Siemens 1FT7082-5WC7X-1XXX is a premium SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for precision motion control and continuous-duty industrial applications. Equipped with an efficient water-cooled system, this servo motor delivers excellent thermal stability, high torque density, and outstanding positioning accuracy. It integrates seamlessly with Siemens SINAMICS S120 servo drive systems through the DRIVE-CLiQ interface, making it an ideal choice for CNC machine tools, robotics, rotary tables, packaging machinery, printing equipment, and automated production systems.
Operating at a rated speed of 2,000 RPM, the 1FT7082-5WC7X-1XXX provides an optimum output power of 4.40 kW, 21 Nm rated torque (100 K), and 21 Nm stall torque (100 K). The motor can deliver up to 55 Nm maximum torque while supporting a maximum mechanical speed of 8,000 RPM, ensuring rapid acceleration, precise positioning, and reliable long-term performance in demanding industrial environments.
The 1FT7082-5WC7X-1XXX family is available in multiple MLFB configurations with various encoder technologies, shaft options (plain shaft or fitted key), optional holding brakes, connector orientations, and protection classes. All variants feature IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication for simplified commissioning and advanced diagnostics.
