Description
Product Description
The Siemens 1FT7138-5AB7X-1XXX is a member of the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for heavy-duty industrial motion control applications that demand exceptional torque, high dynamic response, and outstanding positioning accuracy. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor family is ideal for CNC machining centers, metal cutting and forming machines, industrial robotics, packaging systems, material handling equipment, and other high-performance automation solutions.
Operating at a rated speed of 1,500 RPM, the 1FT7138-5AB7X-1XXX series delivers 17.0 kW rated output power, 108 Nm rated torque, and 170 Nm stall torque (100 K). The motors provide a maximum torque of 590 Nm, offering excellent overload capability and dynamic performance for demanding servo applications. The permanent magnet synchronous design delivers high efficiency, low rotor inertia, smooth operation, and precise speed and position control.
The 1FT7138-5AB7X-1XXX family is available in numerous MLFB configurations with different encoder systems, shaft versions (plain shaft or keyed shaft), optional holding brakes, connector orientations, and balancing grades. All variants feature natural cooling, IM B5 flange mounting, integrated Pt1000 temperature monitoring, DRIVE-CLiQ communication, and rotatable power connectors for simplified installation and commissioning. The exact configuration is determined by the complete Siemens MLFB ordering code.
