The working principle of the eledtro-mechanical conversion of the rare earth giant magnetostriction and its application in fluid control

摘要

In this paper the kinds and main physical characteristics of the RE-GMSM material are given. Also the performance priority of using the large, magnetostrictive characterstics to implement the electro-mechanical conversion, thus driving the load, and the basic design method of this kind of energy converter are discussed. A new method of fluid control is proposed.
