For applications that rely on computer numeric control, servo motors are the favoured type of motor.
A servo motor CNC machine is capable of applying rivets and fastening sections with optimal efficiency, and this allows manufacturers to boost productivity and deliver superior components for industrial automation with far less overhead than would otherwise be possible.
All these assets are due to the reliability of the electric ac servo motor, which can run rotary and linear applications with exact speed and precision.
When it comes to fastening aircraft parts, there's no risk of over or under-fastening, because movements are controlled to their exact end point.
