Description
Product Description
The Siemens 1FT7134-5AB7X-1XXX belongs to the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for high-performance motion control applications requiring exceptional torque, dynamic response, and positioning accuracy. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor family is ideal for CNC machining centers, industrial robotics, material handling systems, packaging machinery, printing equipment, woodworking machines, and automated manufacturing lines. The SIMOTICS S-1FT7 series is recognized for its high power density, low rotor inertia, and reliable operation in demanding industrial environments.
Operating at a rated speed of 1,500 RPM, the 1FT7134-5AB7X-1XXX series delivers 12.9 kW rated output power, 82 Nm rated torque, and 118 Nm stall torque (100 K). The motors provide up to 390 Nm maximum torque, 95% efficiency, and excellent overload capability, making them suitable for high-precision servo applications requiring rapid acceleration and accurate positioning.
The 1FT7134-5AB7X-1XXX product family includes multiple MLFB variants with different encoder technologies, shaft styles (plain shaft or fitted key), holding brake options, connector orientations, and vibration grades. All models feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, integrated Pt1000 temperature monitoring, and rotatable power connectors. The exact configuration depends on the complete Siemens MLFB ordering code.
