Description
Product Description
The Siemens 1FT7084-5SC7X-1XXX is a high-performance SIMOTICS S-1FT7 permanent magnet synchronous servo motor designed for demanding industrial motion control applications that require high torque, excellent positioning accuracy, and continuous-duty reliability. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems via the DRIVE-CLiQ interface, this forced-ventilated servo motor delivers outstanding dynamic response and energy-efficient operation for CNC machine tools, robotics, packaging equipment, metalworking machinery, and automated production systems.
The 1FT7084-5SC7X-1XXX motor family operates at a rated speed of 3,000 RPM and delivers an optimum output power of approximately 8.48 kW, 27 Nm rated torque (100 K), and 35 Nm stall torque (100 K). It provides up to 90 Nm maximum torque and supports a maximum mechanical speed of 8,000 RPM, making it ideal for applications requiring rapid acceleration, high overload capability, and precise motion control. Forced ventilation enables stable thermal performance during continuous high-load operation.
The 1FT7084-5SC7X-1XXX family includes numerous MLFB variants with multiple encoder technologies, shaft versions (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and IP protection classes. All variants feature IM B5 flange mounting, integrated temperature monitoring, and DRIVE-CLiQ communication for fast commissioning and diagnostics. The final motor configuration depends on the complete Siemens MLFB ordering code.
