Non-contact magnetic gear for micro transmission mechanism

Abstract

A unique transmission mechanism using a non-contact magnetic gear (NCMG) is proposed for micro and miniature electromechanical systems. A miniature NCMG has been produced and the basic characteristics were evaluated experimentally. The theoretical approach for analyzing the transmittable torque of the NCMG was developed and verified experimentally. It is concluded that the NCMG system has great potential for use in safe miniature transmission mechanisms for medical applications and in micro transmission systems for microelectromechanical systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
