Using Piezoelectric actuators.
Posted: Wed Nov 22, 2023 4:59 pm
My research started with using Piezoelectric actuators. They are an excellent match with small polymeric fans. The small deflection, low force and low power are a really nice match. However, when I experimented with metallic fan blades and increasing the size of the fan, I could tell that I was limited by the deflection, force and power of these actuators. I purchased the most powerful actuators I could find https://www.thorlabs.com/newgrouppage9. ... p_id=10958 and https://www.piezodrive.com/actuators/pi ... actuators/ . These could only hint at the performance that the steel fans were capable of, so I had to abandon them for electromagnetic motors.
