The measurement of the electrical parameters of ultrasonic motor means that the voltage and current is tested in the process of starting-up,working and stopping of the ultrasonic motor. The conventional instruments can not satisfy these measurement requirements. In this work,an electrical parameters testing system of linear ultrasonic motor has been constructed based on Lab VIEW sorfware platform by using the high-speed data acquisition card, Hall voltage sensor and Hall current sensor.The testing system can measure the instantaneous value and virtual value of voltage and current simultaneously in the process of starting-up,working and stopping of the ultrasonic motor.The measurement error of the system was analyzed and the algorithm error was also given.At last,one linear ultrasonic motor were tested by the system, and the results showed that the testing system was creditable and reliable.
