摘　　要：为简化超声电机的驱动电路 ,采用了自振荡电路这种新型的驱动方法 ,提出了用自振荡电路来驱动电机的类型 ,分析了电路原理。从实验上证实 ,当温度变化时 。A driving circuit for USM is very complex,it needs a frequency automatic follow-up circuit to follow up the resonant point.To simplize the circuit,a self-oscillating ciruit is to be constructed.its frequency is adjustable to the resonant frequency.Here it is successfully used to drive and control USM.In this paper,we expatiate the principal of self-oscillating circuit and point out which type of USM allows to use a self-oscillating circuit.
