Description
Product Description
The Siemens 1FT7102-5WB7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for precision motion control and continuous-duty industrial applications. Featuring water cooling, this servo motor delivers high continuous torque, excellent thermal stability, and outstanding positioning accuracy. It integrates seamlessly with Siemens SINAMICS S120 drive systems through the DRIVE-CLiQ interface, making it ideal for CNC machine tools, industrial robotics, rotary tables, packaging systems, metal processing equipment, and automated production lines.
Operating at a rated speed of 1,500 RPM, the 1FT7102-5WB7X-1XXX delivers an optimum output power of 7.85 kW, 50 Nm rated torque, and 50 Nm stall torque (100 K). The motor can produce up to 130 Nm maximum torque while supporting a maximum mechanical speed of 6,000 RPM, ensuring smooth acceleration, exceptional dynamic response, and reliable operation in demanding industrial environments.
The 1FT7102-5WB7X-1XXX family is available in multiple MLFB configurations with various encoder systems, shaft options (plain shaft or keyed shaft), 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.
