Ultrasonic motor(USM)is a new kind of working mechanism
which applies piezoelectric vibration and frictional force as the driving source.USM speed control ways have voltage-regulation speed-regulation
variable-phase speed-governing and variable-frequency speed-governing.The speed control characteristics of the USM are analyzed.It is achievable for the system simulator based on LabVIEW
an integral platform including data acquisition
analysis
processing and output is built up.The fundamental theory and the compiling features of LabVIEW software are introduced.LabVIEW is used to simulate for speed control of the USM.This software is conveniently
