    摘要: A vibrator of a vibration wave linear motor comprises two and one driving contacting parts respectively on top and bottom surfaces. A first guide member contacts the two driving contacting parts on the top surface, and both ends of a second guide member are pressed upward by spiral springs, and pressing forces are applied respectively between the driving contacting parts and the first and the second guide members. The three driving contacting parts convert elliptical vibrations, which are generated by applying a voltage to a vibrator unit, into driving force, whereby the vibrator self-runs in a direction indicated by a bidirectional arrow d with reference to the first and the second guide members. the self-running of the vibrator is conveyed, via a pin member and an engaging protruding part, to the lens frame, which then slides.

    摘要: With the invention, both a longitudinal vibration mode and a flexural vibration mode are independently detected, or only the longitudinal vibration mode is detected, without using a special device. The invention provides an ultrasonic motor including electromechanical transducers for driving, electromechanical transducers for vibration detection, and an ultrasonic vibrator in which, by supplying two-phase alternating voltages with a predetermined phase difference and predetermined driving frequency to the electromechanical transducers for driving, two different vibration modes are simultaneously generated to produce a substantially elliptical vibration at an output. It is possible to independently detect both the longitudinal vibration mode and the flexural vibration mode with the electromechanical transducers for vibration detection.

    摘要: An ultrasonic motor that is capable of stable driving by preventing uneven rotation of a driven body and maintaining the drive efficiency is provided. The ultrasonic motor includes a plurality of ultrasonic transducers including alternately stacked first piezoelectric elements and second piezoelectric elements, and a control unit for applying the same two-phase driving AC voltages to the plurality of ultrasonic transducers. The ultrasonic motor simultaneously generates longitudinal vibration and flexural vibration at the ultrasonic transducers to generate substantially elliptic vibration at output ends of the ultrasonic transducers and relatively moves the ultrasonic transducers and a driven body in contact with the ultrasonic transducers. The control unit includes a vibration detection circuit that detects the vibrations of the ultrasonic transducers and outputs an average-vibration detection signal, a phase comparator circuit that detects a phase difference between one of the two-phase driving AC voltages applied to the ultrasonic transducers and the average-vibration detection signal, and a frequency control circuit that controls the frequency of the driving AC voltages such that the phase difference detected by the phase comparing part is a predetermined value.
