The power efficiency of linear piezoelectric motors, specifically the inchworm motor, is primarily determined by the relationship between electrical power input and mechanical power output. To calculate efficiency, one must derive the mechanical power from the motor's speed/force curve and divide it by the electrical power input. While the motor itself can exceed 99% efficiency, the overall system efficiency is influenced by the design of the electronic controller and driver, which can introduce inefficiencies, particularly in low-power applications. Energy harvesting during operation is generally inefficient due to high voltage and low current characteristics of piezo elements.

If you cannot find it directly, then you need to calculate it from a piezo motor datasheet. Here is the method:Ahmedbadr132 said:I want to know the power efficiency of linear piezo electric motors in percentile.
The motor alone may be greater than 99% efficient, but the piezoelectric motor does not operate alone, it requires a controller and a driver.Ahmedbadr132 said:I want to know the number .
I did not find a number on the internet.
They just say it is efficient .
