摘要： A control apparatus for a vibration type actuator is disclosed, with which at least three kinds of vibrations are excited, and a desired motion can be carried out with high efficiency. The vibration type actuator includes a rotatable moving member, an elastic member contacting the moving member, and an electro-mechanical energy conversion element exciting at least three different kinds of vibrations in the elastic member by supplying at least three periodic signals having different phases. The control apparatus includes a rotation axis determining unit, a parameter determining unit and a control circuit. The rotation axis determining unit determines a rotation axis for rotating the moving member. The parameter determining unit determines, by using an inverse model, phase and amplitude of the periodical signals.

摘要： A vibration driven motor comprises a bar-shaped elastic member and a piezo-electric element for causing a plurality of bending mode vibrations having a predetermined phase difference therebetween in a plurality of planes of the elastic member in order to drive a movable body by a rotary motion caused in particles of the elastic member. A support member which extends along an axial center of the bar-shaped elastic member is provided at one end or each end of the elastic member.

摘要： In a vibration wave driven motor, when the radius of the arcuate portions and the length of the straight portions of a track type resilient member (21) of an elliptical shape having straight portions and arcuate portions are (R) and (L), respectively, the ratio (R/L) is made equal to or greater than a particular value, whereby the resonance frequencies of two standing waves can be made coincident with each other and the torsion component of the straight portions can be reduced or the direction of the torsion can be made uniform with a result that the driving characteristic in the straight portions can be improved and also the electrode pattern of a piezo-electric element can be simplified.
