摘　　要：对纵扭复合型超声波电机进了结构设计,试制作了样机,进行了实验。在实验中发现,采用增加纵振陶瓷晶堆的厚度这种频率简并方法可使纵、扭谐振频率更为接近,并能提高纵振幅度,这种频率简并方法是简单有效的。A ultrasonic motor using longitudinal and torsional mode was designed, a prototype motor was devised and tested. The experimental tests and analysis show that to increase the depth of piezoelectric ceramic in the longitudinal vibration can increase the longitudinal vibration＇s amplitude and can make the frequencies of longitudinal and torisonal vibration much closer. The frequency matching method is simple and effective.
