MAGNETOSTRICTIVE LINEAR MOTOR BASED ON SELF-MOVING CELL CONCEPT

초록

This research work concerns with the design and test of an magnetostrictive linear motor(MLM) that operates based on self-moving cell concept. The moving cell is composed of Terfenol-D linear actuator and a ring structure, and a cell train is constructed by connecting two cells in series. Since this motor uses the stroke of Terfenol-D actuators and friction force of the cells, it can essentially produce long stroke and large force. The overall performance of the MLM was measured in terms of speed and force. The pushing force is directly related with the friction force. This research is a proof-of-concept stage and more investigation is necessary for realistic application.
