Piezoelectric motor working principle. An example is the camshafts that drive the intake and exhaust valves in internal combustion engines, driven by the engine itself. Piezoelectric motors use a piezoelectric, ceramic element to produce ultrasonic vibrations of an appropriate type in a stator structure. Piezoelectric motors: Piezoelectric elements apply a directional force to an axle, causing it to rotate. In contrast to traditional electromagnetic motors, which generate motion through the application of magnetic fields, piezoelectric motors generate motion through the physical deformation of piezoelectric materials. Piezoelectric effect is very useful within many applications that involve the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, robotics, medical engineering, high power applications, sensors, piezoelectric motors ultra fine focusing of optical assemblies. There are a number of linear and rotary principles based on slow or high-frequency oscillatory motions. Sub-Nanometer Resolution Piezo Linear Motor - V8 Piezo Motor with Zygo Interferometer by Physik Instrumente USA - Precision Motion Control The Johnson Electric Group is a global leader in electric motors, actuators, motion subsystems and related electro-mechanical components. The elliptical movements of the stator are converted into the movement of a slider which is pressed into frictional contact with the stator. Another example is the mechanism that strikes the hours in a traditional grandfather clock or cuckoo clock.
