Abstract
In this paper, noble electrical equivalent circuit ultrasonic motor is applied by model of parallel one from mechanical equation of piezoelectric device and characteristics estimation is done by equivalent converter. Uitrasonic motor is driven by oscillation circuit of two-phase high frequency inverter. Operating frequency of inverter is described by tracking control method of resonance frequency, according to change of load, temperature etc.
