Ultrasonic Motor - Study Mafia

Ultrasonic motor construction tends to be simpler than EM type motors. Fewer assembly parts mean fewer moving parts and consequently less wear. The number of components required to construct an USM is small thereby minimizing the number of potential failure points. As the ultrasonic motor uses ultrasonic vibrations as its driving force,it ...
