Description
Product Description
The Siemens 1FT7105-5AC7X-1XXX belongs to the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for demanding motion control applications requiring high torque, precision positioning, and exceptional dynamic performance. 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 equipment, printing presses, semiconductor manufacturing, and automated production lines.
Operating at a rated speed of 2,000 RPM, the 1FT7105-5AC7X-1XXX series delivers 8.0 kW rated output power, 38 Nm rated torque, and 50 Nm stall torque (100 K). The motors provide up to 200 Nm maximum torque and support maximum mechanical speeds of 6,000 RPM, offering excellent overload capability, rapid acceleration, and highly accurate speed and position control. The permanent magnet synchronous design ensures high efficiency, low rotor inertia, and reliable continuous-duty operation.
The 1FT7105-5AC7X-1XXX product family includes numerous MLFB variants with different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, and protection classes. All variants feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, integrated motor temperature monitoring, and rotatable power connectors. The exact electrical and mechanical configuration is determined by the complete Siemens MLFB ordering code.
