1FT7 – The Compact, Synchronous Servomotor For High-Performance Applications

1FT7 Servo Motors

With highest accuracy in travel between points, 1FT7 servomotors satisfy the highest demands with respect to dynamics, speed setting range, as well as field weakening, true running, and positional accuracy. Equipped with the latest vibration-insulated encoder technology, these servomotors allow field replacements without rotor and encoder alignment, and are optimized for use in fully digital drive and control systems. 1FT7 servomotors are available in IP ratings 64 to 67 with a very high overload capability (up to 4 times rated torque) and rotatable connectors.
