Using a Piezoelectric Actuator for Precision Movement Control


Sharing is caring!

When it involves precision movement control, few actuator kinds can match the exactness of piezoelectric actuators. This has normally made these actuators the recommended actuation solution in a myriad of applications. This post elucidates on the a number of desirable characteristics shown by piezoelectric positioning systems.  These actuators have actually been commercially offered for 35 years, and have actually constantly adjusted and advanced during this period. Quartz, barium titan ate, lead neonate, and lead zircon ate titan ate are some examples of piezoelectric materials.

Multilayer Piezo Actuators

The two significant residential or commercial properties of piezoelectric materials are:

  • They produce an electrical voltage when stress is applied to them.
  • They mechanically deform in reaction to a used electrical charge/voltage.

The whole variety of piezoelectric actuators is built on these basic concepts. Below are some key residential properties of piezoelectric actuators that make them the preferred option in precision motion control:

– Limitless resolution: Piezoelectric actuators do not make up relocating components, as they directly transform electric energy into power, and vice versa. The lack of relocating parts enables limitless resolution.

– Receptive actuation: Such actuators are highly responsive, and react to electric exposure in a couple of microseconds or less. These actuators could even give velocity rates as much as 10,000 g as well as a lot more.

– Ability to generate high pressure: With the evolution of piezoelectric actuators, it is now feasible to move loads of numerous tons. Despite these loads, the linear motor/actuator can control travel varieties of up to 100 micrometers with sub-nanometer resolutions.

– Piezoelectric actuators are best fit for such applications due to the fact that the piezoelectric impact is primarily related to electric areas. Such a straight motor/actuator is not affected by electromagnetic fields. They also do not create magnetic fields of their own.

– Power efficiency: Even when these actuators are needed to hold hefty loads for a long time, they do not show a significant energy loss. Static operation hence comes to be surprisingly energy and cost-effective. Merely specified, these actuators are capable of storing power just like an piezoelectric supplier.

In addition to the functions discussed over, piezoelectric actuators are additionally efficient in operating typically in vacuum cleaner settings where quality precision motion control is called for. And, they are compatible for use in clean area applications as they do not require making use of lubes. Additionally, if your application requires an actuator that can work at cryogenic temperatures, you could request your maker to create a special actuator matched to such settings.

Provided these qualities, piezoelectric actuators are increasingly preferred for precision movement control in information storage space, semiconductors, life science and medical modern technology, precision auto mechanics, optics, photonics, and so forth.
