Abstract
The piezoelectric motor is a new type of electrical drive utilizing the inverse piezoelectric effect for electromechanical energy conversion. Piezoelectric motors exhibit very high torques at low speed levels. When the electrical power source is switched off, the rotor is clamped due to high frictional forces, making this motor ideal for a variety of positioning tasks (gearless systems). Additional advantages of piezoelectric motors are a very low noise emission and the absence of magnetic interference
