These include a piezoworm stage and a USM with segmented electrodes. Two examples of piezoelectric motors are discussed in detail. Several designs from the literature and commercial suppliers are reviewed and their characteristics are presented. In this chapter, these motors are classified into quasistatic and ultrasonic motors (USMs) based on their working frequency. Piezoelectric motors use actuators that take advantage of the converse piezoelectric effect. This is due to their unique characteristics including their very high accuracy and short response time as compared to electromagnetic based motors and actuators and higher output force compared to electrostatic actuators.
