Abstract:  Ultrasonic Motor (USM) is a new kind of direct driving motor, characteristic test of USM is the base of control. A testing and analyzing system of USM was built by virtual instruments, it realized testing and analyzing multi-parameter, such as voltage, current, and votary etc. of rotary ultrasonic motor and linear ultrasonic motor, in process of steady state and transient, and built a stable and reliable test platform. The system is simple, practical and feasible.
