Abstract

This paper deals with the feasibility assessment of hybrid linear motor that operates based on self-moving cell concept. The moving cell is composed of Magnetostrictive actuator and a ring structure, and a cell train is constructed by connecting two cells in series. Since this motor uses strong push force of Terfenol-D actuators and friction of the cells, it can essentially produce long stroke and large force. The overall performance of the motor was measured in terms of speed and force.
