Small in size, large in power: Piezo motors
Piezoelectric motors can be used in a variety of applications due to their exact movements and the compact nature of their design. Piezo motors can duplicate a motion many thousands of times without sustaining wear and tear the way a traditional motor design would. This is due to the deforming and responsiveness of the ceramic and other materials.
Another reason why piezo are leveraged in different situations is their ability to stack and attain a wider range of motion and scale than conventional motor setups. Having the ability to extend the plane of motion by simply adding another piezo motor on top of an existing unit means manufacturers can scale these systems to large proportions while still benefiting from their small number of moving parts, high reliability and extreme accuracy of movement.
Another advantage of a piezo motor system is the ability to apply both digital and analog DSP systems in their design. These motors were designed to receive an electrical signal to complete their movement and they can be quickly connected to either type of system to interface and operate remotely. Since the displacement or movement of the element is proportional to the drive voltage, if the sending device can generate the correct voltage range, a piezo motor will favorably operate to control elements without requiring any additional components.
A piezo motor system has only ceramic design components in its structure. This means that ferrous materials, copper and other pieces of metal or plastic that could harm the environment are removed and the structure can be used knowing it is “clean and green.” The high torque produced by the motor means there are no compromises needed to create a design with high-resolution movement, reliable operation and a structure that is scalable at the same time. This cannot be said of other electric small motor technologies.
