Ultrasonic Piezomotors [PLUS × 2027]
: The stator's contact points typically move in an elliptical path, providing tiny "micro-impulses" that result in smooth, continuous motion.
The heart of an ultrasonic motor is the , usually a piezoelectric ceramic like PZT (Lead Zirconate Titanate). When an oscillating voltage is applied, the stator undergoes high-frequency deformations. ultrasonic piezomotors
