摘要： A piezoelectric motor has peak performance at a specific frequency f1 that may vary over a range of frequencies. A drive system is disclosed for operating such a motor at peak performance without feedback. The drive system consists of the motor and an ac source connected to power the motor, the ac source repeatedly generating a frequency over a range from f1−&Dgr;x to f1+&Dgr;y.
