Description
Product Description
The Siemens 1FT7136-5SB7X-XXXX is a heavy-duty SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for high-torque industrial motion control applications. Engineered for seamless integration with Siemens SINAMICS S120 servo drive systems through the DRIVE-CLiQ interface, this forced-ventilated servo motor delivers exceptional torque density, outstanding overload capability, and precise positioning performance. It is ideal for heavy CNC machine tools, metal cutting and forming machinery, rotary tables, presses, robotics, and other demanding industrial automation systems.
Operating at a rated speed of 1,500 RPM, the 1FT7136-5SB7X-XXXX provides 31.4 kW optimum output power, 200 Nm rated torque (100 K), and 235 Nm stall torque (100 K). The motor can produce up to 510 Nm maximum torque while supporting a maximum mechanical speed of 3,600 RPM, making it suitable for applications requiring extremely high torque, rapid dynamic response, and continuous heavy-duty operation. Forced ventilation ensures reliable thermal performance under sustained high-load conditions.
The 1FT7136-5SB7X-XXXX product family is available in multiple MLFB variants with different encoder systems, shaft configurations (plain shaft or fitted key), optional permanent-magnet holding brakes, connector orientations, vibration grades, and protection classes. All variants include forced ventilation, IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication. The exact configuration is determined by the complete Siemens MLFB ordering code.
