Description
Product Description
The Siemens 1FT7042-5AF7X-1XXX belongs to the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, designed for high-precision motion control in compact industrial automation systems. Optimized for seamless integration with Siemens SINAMICS S120 servo drive systems, this motor delivers exceptional positioning accuracy, fast dynamic response, and high efficiency for applications including CNC machinery, robotics, packaging equipment, semiconductor manufacturing, printing machinery, and automated assembly systems.
With a rated speed of 3,000 RPM, the 1FT7042-5AF7X-1XXX delivers 0.85 kW rated output power, 2.7 Nm rated torque, and 3.0 Nm stall torque (100 K). The motor is capable of producing 13 Nm maximum torque and supports maximum mechanical speeds up to 9,000 RPM, providing excellent acceleration, smooth operation, and precise speed control. The permanent magnet rotor design ensures high efficiency, low rotor inertia, and outstanding servo performance.
The 1FT7042-5AF7X-1XXX family includes numerous MLFB variants with different encoder technologies, shaft configurations (plain shaft or fitted key), optional holding brakes, connector orientations, protection classes, and vibration grades. All variants feature natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, and an integrated temperature monitoring system. The exact configuration is determined by the complete Siemens MLFB order number.
