Smart electronics reduce energy consumption and improve performance of piezoelectric ultrasonic motors
May 16, 2013 2:10 pm | by David Henderson, co-CEO, New Scale Technologies, Inc., www.newscaletech.com | Articles | CommentsPiezoelectric ultrasonic motors (piezo motors) are a distinct class of rotary and linear actuators requiring unique driving circuits to achieve practical, reliable, precise and efficient operation. A piezo motor uses the ultrasonic vibrations (greater than 20 kHz) of a “stator” structure that is frictionally coupled to a moving slide or rotating shaft. Piezo motors with operating frequencies from 40 to 700 kHz are commercially available.
