초록
A linear actuator using Terfenol-D rod which can accumulate displacement of the rod was fabricated. The diameter of used rod is 12[mm] and the length of it is 75[mm]. It adopts the electromagnetic units as the clamping units. Basic characteristics of the linear actuator such as displacement vs. current, velocity vs. frequency, step size vs. frequency were experimented. When the driving current is 1[A] and 100[Hz], the velocity of the actuator is about 3.5[mm/s]. We discussed the cause of step size's decrease as increasing driving frequency and the solution to the problem.
