Title: Ultrasonic motor
Inventor: TSUKUI MICHIO
IPC: H02N2/00
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic motor which is simple in structure and is capable of producing multiple outputs. SOLUTION: An elastic body 2 fixed in a case 1 is provided with an inner annular section 4 and an outer ring-shaped section 5, which are separated from each other in the radial direction by a circumferential groove 2b and serve for a plurality of resonators. A piezoelectric body 7 is pasted on the bottom faces of these annular sections. Each of the ring-shaped sections is formed with a comb-like tooth section 4a (5a). With outer wall sections 8b, 9b of independent rotors 8, 9 which are resiliently in contact with the comb-like tooth sections of the annular sections respectively, high frequency voltage having a resonance frequency of either the annular section 4 or 5 is applied to the piezoelectric body 7 from an AC power supply 11 to drive a corresponding rotor.  A connection flange section 6 which is the bottom wall of a circumferential groove is located on the vibration neutral faces of the ring-shaped sections. By using such a simple structure in which a circumferential groove is provided in one elastic body and the bottom wall of the groove is located on the vibration neutral faces of annular sections, a multishaft ultrasonic motor which has no propagation of vibration between the two annular sections and can deliver independent driving forces can be obtained.
