Magnetic Circuit Design Method for Magnetic Force Control Systems Using Inverse Magnetostrictive Effect

摘要

A new magnetic force control method using giant magnetostrictive material (GMM) was proposed and its feasibility was confirmed in the former studies by the authors. This new method is based on the inverse magnetostrictive effect and the magnetic force is controlled by changing the stress or strain in the magnetostrictive material. This method was expected to have lower heat generation and higher energy conversion efficiency compared to traditional methods since constant magnetic force can be maintained by only applying constant stress.
