Abstract: Exciting coil is the electromagnetic conversion component, which mainly provides the driving magnetic field for Giant Magnetostrictive Actuator (GMA) and controls its output displacement, and can adjust inputting different current. Therefore, optimizing design the structural parameters and selecting appropriate material of the exciting coil is the key factor to improve the electromagnetic conversion efficiency and give full play to the characteristics of Giant Magnetostrictive Materials (GMM) materials. In this study, the uniformity of magnetic field intensity on the center axis of GMM rod is regarded as the evaluation standard and main design principle by analyzing the working principle of GMA. Exciting coil material is selected through analyzing of its magnetic permeability and the design parameters of exciting coil is optimized by analyzing important factors such as magnetic field intensity and heat loss. Finally, the magnetic circuit of excitation coil is analyzed by using Ansoft Maxwell finite element method. The simulation result shows that the distribution of magnetic field is more uniform and its uniformity is improved to be 98.65%. -
