Surface acoustic wave motors

摘要：

Surface acoustic waves (SAWs) excited by interdigital transducers (IDTs) deposited on piezoelectric materials have been used for manufacturing acoustic motors including linear and rotary motors,which have the similar characteristics as conventional ultrasonic motors and several additional advantages,such as high operation frequencies,high energy density and easy miniaturization,etc.Recently,several types of non-contact SAW motors have also been developed to improve the operation performances.In addition,the driving mechanisms of the motors were analyzed and discussed.
