Paper Title:
Design and Simulation of a Mini Precision Positioning Magnetostrictive Inchworm Linear Motor
  Abstract

Giant magnetostrictive actuator (GMA) has advantages over other actuator made of intelligent materials in aspects like quick response, large output force, and high precision. But the lack of displacement, relatively big size and heavy weight block its popularization. In this paper, a new mini linear motor based on three GMAs is designed. It is the second generation motor derived from the improvement of the first generation linear motor that is realized in our previous work. To compensate the structural defects and to improve the traveling performance of the previous one, we redesign the motor in the structure, especially the frame as a whole by considering not only the basic supporting and connecting role but also the displacement amplifying function in it. The paper presents the process of the structural design of the mini linear motor, the establishment of the motor’s system dynamic model and the traveling simulation under SIMULINK. The new structural scheme and the motor’s system modeling approach are validated by the simulation results. Keywords: magnetostrictive; inchworm linear motor; structural design; dynamic modeling
