a piezo motor utilizes the piezoelectric effect, or the tension that forces a multilayered material, like quartz or rochelle salt, to bend when charged with an electric current. our company is professional hydraulic motor,piston motor,pg电子下载-pg电子游戏,gearbox,hydraulic steering unit supplier providing customers from domestic zhongyiyepk and overseas the best and reliable hydraulic products.welcome to visit our website.it does not cause or need magnetic fields, and it's not influenced by them. in that regard, the piezo motor runs more precisely compared to a normal electric motor. it's very little, amazingly strong, rapid and contains neither rotors nor gears.
one time i saw a piezo motor that was the size of a sugar cube. it couald maneuver several centimeters at once and could lift just about 1000 times its own weight.
inside workings
the piezoelectric motor has been used in microchip development for many years, so it isn't a new idea. zirconate, lead and titanate powders are refined, morphed to shape, fired, charged, polarized, and tested. to reach polarization, electrical fields are used to align the piezoelectric materials along a primary axis.
it may seem complicated, but the motor functions the same way that substances that contain iron are magnetized. after electricity is applied, it uses its poled ceramic design to create movement through periodic, sinusoidal electrical fields.
the ceramic side is joined with a precision stage, and the resulting driving force from the piezo motor generates stage motion. depending on how the combining device is constructed, a piezoelectric motor can travel both linearly and in rotationally. the periodic nature of the driving current allows for limitless travel and steady motion.
types of piezoelectric motors
this type of motor has been developed in several different ways for many different uses. the traveling-wave piezo motor is utilized for auto-focus in reflex cameras and the inchworm motor moves linearly. some piezoelectric motors are employed in camera sensor displacement technology, permitting anti-shake features.
the motor can be used in portable products, healthcare technology products, the automotive industry and in digital household electrical appliances. the piezoelectric motor is becoming a lot more cost-effective, even for mass volume uses in high-precision systems.
how to choose a supplier?if your quantity is small, you can go to a local wholesaler, but if you want to order more, go directly to a factory will be more cost-effective. ningbo zhongyi hydraulic motor co., ltd will can provide superior-quality hydraulic motor, pg电子下载-pg电子游戏 piston motor, hydraulic winch,axial piston motor pg电子下载-pg电子游戏 products and satisfactory service.
