If you are new to piezo ring actuator then they are basically a ring which is made up of polymer coating and used to offer high force.
It is in the round shape so as it can meet the optics or microscopy demands. You can see this in various things like microphone, earphones and much more.
Essential things about ring actuator
Piezoelectric ceramics is made up of very stable material which is insulated too. That stable material helps the actuator to perform well under the harsh environment and also it is light weighted. You can easily carry it from one place to another.
The OD/ID is also there which varies on your project requirement. You can get this with wire or without wire that is up to you. Its life is really superior as you will get to notice once you start using it and also it is highly reliable too that you will get to know later on.
What are the uses you should know?
There are many different uses of the piezo ring actuator like it is used to adjust machining tools, adjusting lens mirrors and many other equipment.
It can also be used like a volume pump or for the special purpose motor. There are different applications in which you will get to see it.
This device is used in both mechanical and electrical field and used to control any kind of energy into the controlling motion.
It does not matter the type of energy as it can convert every single one of them on your command. In this way it works and also you can find it in various devices too.
