Notes:
Piezoelectric motors have been successfully developed for various applications likeautofocus drives in camera lenses and manufacturing equipment for semiconductor production. Theirhigh speed and accurate positioning capability, combined with a moderate holding torque, makepiezo motors also very attractive for actuation purposes in spacecraft mechanisms. However, thesemotors require high driving voltage and have only a small driving torque. In this paper, the authorshave developed a novel magnetostrictive rotary motor using Terfenol-D (Tb0.3Dy0.7Fe1.9) material asthe driving elements. The small movement of the magnetostrictive actuator is scaled to 3 times byusing flexible flexure hinges, a special designed mechanism is used to combine 3 such actuators toform a pure rotation movement and this movement is used to drive the rotor of the motor. Prototype ofthis 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 ofHangzhou Dianzi University
