利用两相谐振电压变换器搭建了测试平台,通过调节两相驱动电压的振幅、频率和相位差,对三种行波型超声波电机的调速方法进行了研究和比较。结果表明,调频调速比调压调速和调相调速更为灵活,且具有较大的调速范围。这一结果为超声波的电机的控制策略的进一步研究提供了借鉴。

In this study,An experimental test set-up of USM is developed to examine the speed control methods of a travelling wave ultrasonic motor.Experimental results are taken from the ultrasonic motor drive and control system by separately applying three control methods which are amplitude,frequency and phase angle controls.According to the experimental results,the method on changing driving frequency gives more flexible control range than the other two methods.
