All of us know that motor is a machine which produces or imparts motion,
or in detail it is an arrangement of coils and magnets that converts
electric energy into mechanical energy and ultrasonic motors are the
next generation motors.
In 1980,the world's first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed, high torque and power to weight characteristics.
Electromagnetism has always been the driving force behind electric motor technology. But these motors suffer from many drawbacks. The field of ultrasonic seems to be changing that driving force.
