Description
Product Description
The Siemens 1FT7136-5AC7X-1XXX is part of the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for demanding industrial motion control applications that require high torque, precise positioning, and exceptional dynamic performance. Optimized for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor family is ideal for CNC machining centers, metal cutting and forming equipment, industrial robotics, material handling systems, packaging machinery, printing presses, and automated production lines. The compact design, high power density, and rugged construction ensure reliable operation in continuous industrial environments.
Operating at a rated speed of 2,000 RPM, the 1FT7136-5AC7X-1XXX series delivers 14.9 kW rated output power, 71 Nm rated torque, and 140 Nm stall torque (100 K). The motor provides up to 490 Nm maximum torque while supporting maximum mechanical speeds of 3,600 RPM. Its permanent magnet synchronous design provides excellent overload capability, high efficiency, low rotor inertia, and accurate speed and position control for demanding servo applications.
The 1FT7136-5AC7X-1XXX product family includes numerous MLFB variants with different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, vibration grades, and protection classes. All models feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, an integrated Pt1000 temperature sensor, and rotatable power connectors. The exact electrical and mechanical configuration depends on the complete Siemens MLFB ordering code.
