Paper Title:
A Novel Magnetostrictive Drive Rotary Motor
  Abstract

Piezoelectric motors have been successfully developed for various applications like autofocus drives in camera lenses and manufacturing equipment for semiconductor production. Their high speed and accurate positioning capability, combined with a moderate holding torque, make piezo motors also very attractive for actuation purposes in spacecraft mechanisms. However, these motors require high driving voltage and have only a small driving torque. In this paper, the authors have developed a novel magnetostrictive rotary motor using Terfenol-D (Tb0.3Dy0.7Fe1.9) material as the driving elements. The small movement of the magnetostrictive actuator is scaled to 3 times by using flexible flexure hinges, a special designed mechanism is used to combine 3 such actuators to form a pure rotation movement and this movement is used to drive the rotor of the motor. Prototype of this research is made and a commonly 3-phase alternating current is used to drive the motor. Experiments are also carried on in the lab of School of Mechanical and Electrical Engineering of Hangzhou Dianzi University.
