    摘要: In a vibration wave driven motor wherein an AC electric field is applied to an electro-mechanical energy conversion element secured to an elastic member to thereby excite a plurality of standing waves differing in phase from each other in the elastic member and a travelling wave is formed in the elastic member by the combination of the standing waves, whereby a member which is in pressure contact with the elastic member and the elastic member are moved relative to each other by a frictional force, provision is made of means for making the contact pressure on the surface of contact between the elastic member and the member which is in pressure contact with the elastic member non-uniform, and means for making the dynamic rigidity of a vibration member non-uniform in an unnecessary vibration mode created by the means for making the contact pressure non-uniform, whereby the occurrence of noise is prevented by simple and inexpensive means.

    摘要: A unit for attenuating frequency components generated in a sideband of a frequency of an AC voltage applied to an electro-mechanical energy conversion element. This attenuation is achieved by modulation performed in a speed control apparatus for a vibration driven motor. The control apparatus includes a filter for cutting frequency components of a smaller frequency difference (fd) or more of an absolute value of a frequency difference between a natural frequency of an n-th order vibration and a natural frequency of an (n-1)th- or (n+1)th-order. A filter output is input to a modulator in a driving circuit, and noise of the vibration driven motor can be greatly reduced.
