Research overview:
A magnetic lead screw which is free from noise and vibration free from friction, and available in vacuum is proposed. The mechanism comprises of a conventional steel lead screw and a magnetic nut which is made from a helically-magnetized permanent magnet. The aim of this study is to clarify the elctromagnetic and mechanical characteristics of magnetic lead screws.
