The Distinctive Characteristics of Piezo Electric Actuators & Motors
For applications that require high levels of accuracy, stability, repeatability and stability, the use of piezo electric actuators is highly recommended. These devices are also referred to as transducers, or translators. The primary function of these actuators is that they can convert electrical energy into linear motion while providing virtually unlimited resolution.
This makes them suited for applications where both precision and heavy load bearing capacities are called for. Besides, there are no gears, motors or other parts that would otherwise be subject to wear and tear. This attribute also eliminates the need for lubrication and maintenance.
Industries can make use of standard as well as custom actuators that come with relevant subassemblies. In the long run, you can expect a superior lifetime of service from these actuators that can be seamlessly integrated in the most critical applications.
Since the requirements of multiple industries invariably differ from each other, there are different types of piezo mechanisms that are available. Each of these mechanisms helps solve different problems. Here are some types of piezo mechanisms that help meet different requirements:
• Direct piezoelectric actuators: These are known for the attributes such as high resistance to humidity and a high amount of stiffness. They are also compatible with ultra high vacuum operations, and also equally suitable for clean room applications. Another defining characteristic is that they demonstrate a very large operating temperature range.
• Flexure lever actuators: They comprise a flexure guiding system that gives them a very good response time. They have a travel range of 480 microns and resolutions up to 0.2 nanometers. Depending on your specific application, you could choose between open and closed loop versions. OEMs stand to benefit from these actuators. The high force actuators available in this category are backlash-free.
• Ultrasonic linear motors: These feature a long travel range of 10s of millimeters. They allow for easy integration as most manufacturers offer them with integrated linear encoders and guiding systems. High forces of up to 8 Newton can be achieved. These are also very stable and as they have a self-locking feature with no heat generation.
Piezo actuators are suitable for different types of applications in industries such as semiconductor technology, biotechnology, life sciences, microscopy, medical design, aerospace and defense, image stabilization, data storage, aeronautics, astronomy and active optics, and precision machining among many others.
There are certain actuator models that are also suited for high load bearing applications. These very attributes are what industries need these days to make rapid progress in their respective fields. Since piezo actuators are a significant investment, it is advisable to purchase these from a leading manufacturer. This will ensure that your investment is protected in the long run.
