Ultrasonic motor and electronic apparatus having an ultrasonic motor |
| abstract |
An ultrasonic motor including an oscillation drivencircuit for generating an oscillation wave by self-excitednoscillation by an oscillator 101 bonded with anpiezoelectric element 102 and start/stop signal generatingnmeans for generating a signal of controlling start/stop ofnthe ultrasonic motor by bringing the oscillation drivencircuit 405 into an active state / stop state in which thenoscillation drive circuit 405 includes a power amplifiernfor amplifying an excitation signal, a capacitive circuitnfor adjusting a frequency of the excitation signal and answitching circuit connected to a capacitive elementnconstituting the capacitive circuit for shortcircuitingnterminals of the capacitive element based on an outputnsignal from the start/stop signal generating means. |
