Piezoelectric motor9/25/2023 ![]() ![]() In a nutshell, piezoelectricity is the process of using crystals to convert mechanical energy into electrical energy or vice versa. Instead of squeezing grapes to make wine, we’re squeezing crystals to make an electric current! Piezoelectricity is in a ton of everyday electronic devices, from quartz watches to speakers and microphones. The word piezoelectric originates from the Greek word piezein, which literally means to squeeze or press. Piezo what? Piezoelectricity sounds like a lot to take in, but it’s simple to understand. Learn how piezoelectricity produces an electric charge by applying mechanical stress to a piezoelectric material. ![]() Keywords- Piezoelectric effect, Nanomotion, Piezoelectric motor, ultrasonic motor, MICROMO.Français (French ) Italiano (Italian ) Deutsch (German ) Motion is generated when the piezoelectric element moves against a static platform. Regarding piezoelectric motors, the piezoelectric element receives an electrical pulse, and then applies directional force to an opposing ceramic plate, causing it to move in the desired direction. Piezoelectric Motors because having very high voltages correspond to only tiny changes in the width of the crystal, this crystal width can be manipulated with better than micrometer precision, making piezo crystals an important tool for positioning objects with extreme accuracy, making them perfect for use in motors, such as the various motor series offered by Nanomotion. The operating characteristics of Nanomotion’s motors provide inherent braking and the ability to eliminate servo dither when in a static position. Nanomotion motors are capable of driving both linear and rotary stages, and have a wide dynamic range of speed, from several microns per second to 250mm/sec. Using piezoelectric technology, Nanomotion has designed various series of motors ranging in size from a single element (providing 0.4Kg of force) to an eight element motor (providing 3.2Kg of force). Piezoelectric materials provided the perfect technology upon which Nanomotion developed our various lines of unique piezoelectric motors. ![]() It is also the basis of a number of scientific instrumental techniques with atomic resolution, such as scanning probe microscopes. 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. When reversed, an outer electrical field either stretches or compresses the piezoelectric material. When piezoelectric material like Berlinite, cane sugar, quartz, Rochelle salt, topaz, tourmaline, is placed under mechanical stress, a shifting of the positive and negative charges. generation of stress when an electric field is applied. One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect also exhibit the converse piezoelectric effect i.e. The word Piezoelectric is derived from the Greek piezein, which means to squeeze or press, and piezo, which is Greek for “push”. Abstract: Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. ![]()
