Siemens SIMOTICS S-1FT7 Synchronous Servo Motor About

The Siemens 1FT7087-7AF71-1KA0 is a SIMOTICS S-1FT7 synchronous servo motor designed for high-performance motion control, CNC machine tools, robotics, and demanding industrial automation applications. It uses permanent-magnet synchronous motor technology and is engineered for precise speed, torque, and position control when paired with Siemens SINAMICS drive systems. The 1FT7087 frame size provides a robust servo solution with high power density and excellent dynamic response. The -7AF71 configuration identifies the motor's electrical, mechanical, and cooling arrangement, while -1KA0 specifies the particular feedback, shaft, brake, and connection configuration. The motor is suitable for CNC axes, machine tools, robotics, handling equipment, production automation, packaging machinery, and precision positioning systems requiring accurate and repeatable motion. Its permanent-magnet design supports efficient operation, rapid acceleration, and reliable continuous-duty performance. For the exact 1FT7087-7AF71-1KA0 MLFB, the rated power, rated torque, rated speed, encoder type, holding-brake specification, protection rating, dimensions, and weight should be verified from the Siemens-specific datasheet rather than inferred from another 1FT7087 variant.
