【Abstract】 A driving circuit model of the traveling wave ultrasonic motor was established and the drive performance of this circuit was simulated.The results showed that the square-wave voltage as driving source was feasible and an appropriate matching inductance did not only affect the resonant state of the motor but also play an important role in optimizing the voltage waveform and boosting voltage amplitude.更多还原
