  • Ultrasonic motor and electronic apparatus having ultrasonic motor
    Patent number: 6081063
    Abstract: An ultrasonic motor has at least one piezoelectric flexing vibration member driven by application of a voltage thereto to undergo flexing vibration. A piezoelectric stretching vibration member is integrally laminated in a lamination direction on the piezoelectric flexing vibration member and is driven by application of a voltage thereto to undergo stretching vibration in a direction generally perpendicular to the lamination direction. A movable body is vibrationally driven by a combination of the flexing vibration of the piezoelectric flexing vibration member and the stretching vibration of the piezoelectric stretching vibration member.
