| Abstract: | By optimizing structure parameters, a new kind of non water cooling micro displacement actuator using Tb 0.3 Dy 0.7 Fe 2 single crystal was designed. The magnetostrictive property of the actuator was determined. Results showed that the maximum linear working rang was within 0.5～35.5μm,working volt within 2～24V, and saturation driving displacement reached up to 39.5μm. |
