Description
Product Description
The Siemens 1FT7102-5AC7X-1XXX is part of the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for high-performance motion control applications requiring exceptional positioning accuracy, high torque density, and reliable continuous-duty operation. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor family is ideal for CNC machine tools, industrial robotics, packaging machinery, material handling systems, semiconductor equipment, printing presses, and automated production lines.
Operating at a rated speed of 2,000 RPM, the 1FT7102-5AC7X-1XXX series delivers 5.03 kW rated output power, 24 Nm rated torque, and 30 Nm stall torque (100 K). The motors provide up to 120 Nm maximum torque while supporting maximum mechanical speeds of 6,000 RPM, ensuring excellent overload capability, rapid acceleration, and precise speed and position control. The permanent magnet synchronous design offers high efficiency, low rotor inertia, and smooth dynamic performance.
The 1FT7102-5AC7X-1XXX family includes numerous MLFB variants with different encoder technologies, shaft configurations (plain shaft or keyed shaft), optional holding brakes, connector orientations, and balancing grades. All models feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, integrated motor temperature monitoring, rotatable power connectors, and IP64/IP65 protection depending on the selected configuration. The exact electrical and mechanical features are defined by the complete Siemens MLFB ordering code.
