The Study on Driving Power of Giant Magnetostrictive Actuator

介绍了稀土超磁致伸缩微致动器的结构、工作原理 ,给出了基于功率MOSFET管的超磁致伸缩执行器驱动电源的电路 ,实验表明该驱动电源可以满足微致动器的工作需要。

First, this paper introduces the architecture and the theory of operation of the giant magnetostrictive actuator. Then based on analysis of the driving character of giant magnetostrictive material and the driving power of giant magnetostrictive actuator, we give a circuit of driving power of giant magnetostrictive actuator on MOSFET. The result shows that the driving power meets the demand of actuator. The elongation of actuator can attain 30 μm and the force of the actuator can attain 911N.
