【摘要】 压电超声波电机的工作原理及其驱动控制方式不同于传统电磁型电机,本文针对该电机的驱动要求,采用脉宽调制技术,研制了一套适合于该电机的PWM变频调速装置,对该装置各组成部分分别作了介绍。实验结果表明,所研制的PWM变频调速装置符合压电超声波电机的驱动要求。更多还原

【Abstract】 The operating principle and driving-controlling method of piezoelectric ultrasonic motor are quite different from the electromagnetic motors.In this paper,based on the drive requirement of the motor,a PWM converter system is presented by taking use of the technique of pulse width modulation.This paper makes a great deal of detailed analysis of each part of the converter system.It is tested that the PWM converter system can be used to drive the piezoelectric ultrasonic motor.更多还原
