Title: Oscillatory wave motor
Inventor: KITANI KOJI
IPC: H02N2/00
Filed: 1987-04-27
Abstract: PURPOSE:To improve efficiency by bringing the wave number of oscillatory waves excited on the circumference of a ring-shaped vibrator and the number of grooves to specific relationship in the ring-shaped vibrator having a large number of the grooves in the radial direction. CONSTITUTION:A ring-shaped piezoelectric body 1 and a ring-shaped vibrator 2, to the whole circumference of which grooves 3 in the radial direction are notched and which consists of an elastic body, are joined with adhesives, etc., thus constituting an oscillatory wave motor together with a ring-shaped moving body. The piezoelectric body 1 has a large number of electrodes 1a partitioned by cut lines 1b, and each electrode 1a has length of lambda/2 (lambda represents a wavelength) and is formed in two groups (A and B phase) displaced in lambda/4. When AC voltage, phase of which is displaced at 90 deg. mutually, is applied to the electrodes in two groups of the A phase and B phase, bending oscillatory waves in a wavelength lambda proceeding in the circumferential direction of the vibrator 2 are generated in the vibrator 2. Accordingly, the ring-shaped moving body brought into contact with the vibrator 2 is friction-driven.
