What is a Piezo Motor? How does it work? Different Designs for Automation & Precision Motion Control

More Piezoelectric motors (piezomotors) are based on solid-state effects in electroactive ceramics. Today, a variety of designs is available, optimized for different applications: PiezoWalk, ultrasonic, stick-slip, ratchet, surface wave, mini-rod, etc. Parameters such as cost, speed, pushing force, holding force, stability and size can be influenced by different designs. This video shows commercially available piezo motors. Piezo motor design principles at:
