Title: Vibration wave motor
Inventor: IZUKAWA KAZUHIRO
IPC: H02N2/00
Filed: 1984-02-06
Abstract: PURPOSE:To enhance the drive efficiency by applying a frequency voltage to an electrostrictive element polarized at the prescribed pitch in the prescribed direction, and driving a movable body by a traveling vibration wave generated at the element. CONSTITUTION:An AC power source 9 is connected between electrodes 121, 122, 123 and electrodes 131, 132, 133 bonded to the front and back surfaces of an electrostrictive element 10, and a voltage of a direction crossing the polarizing direction is applied to the element 10. Then, when the current direction is as designated by an arrow H, the positive polarizing side is elongated and the negative side is contracted. Since the applied voltage is AC, the elongation and the contraction alternately occur to become a vibration wave. Since the vibration wave has a pitch of lambda/4 and a phase difference, it advances and frictionally drive the movable body 3 pressed in contact with the element 10. Thus, since the vibration wave generated by the element 10 is by the slipping vibration of the high electromechanical coefficient, the drive efficiency can be enhanced.
