Description
Summary:This paper presents a low cost, user friendly and effective drive system for the speed control of travelling wave ultrasonic motor (TWUSM). Driving frequency and voltage were used as control inputs in the speed control. Driving frequency was adjusted by semiconductor switches existing in a two-phase half-bridge serial-resonant inverter circuit controlled by digital integrated circuits, whereas driving voltage was adjusted by a high performance power supply which has full bridge inverter and rectifier circuits controlled by a microcontroller. The drive system designed was tested under several operating parameters in Orcad PSpice 9.1. The simulation results obtained have demonstrated effective achievements for the speed control of TWUSM and so the drive system is convenient for the speed control applications.
