This study is proposed with the ideology of zone-energy method to precisely analyze the optimal
driving location of novel ultrasonic actuator. This actuator is designed with the piezoelectric buzzer to act as
its actuating component. It is formed a 3-phase continuous traveling wave by using the asymmetric framework
within the metal plate, it is therefore accessible to actuate the shaft. In order to produce the congruent driving
force caused by 3-phase continuous traveling waves within a periodic pulse, the optimal driving location must
be situated on the eccentric location of buzzer instead of its core. The zone-energy method, in view of the
energy balance, is available to find out the location of eccentric screw. By using this method, it is aimed to
precisely solve out the optimal driving location that is situated on the a-third wavelength distance away from
the circle center and the offset angle of 30ºC apart from a certain screw on the Ni-alloy plate.
Key words: Piezoelectric buzzer, ultrasonic actuator, zone-energy method, , , ,
