ABSTRACT:
An ultrasonic motor drive device capable of prolong the service life of an ultrasonic motor by preventing the motor from being unstably operated when the motor is driven at a lower speed of at least two speeds. When the ultrasonic motor (3) is driven at a rather low speed in normal driving, the motor can be prevented from being unstably operated by its driving at a rather low speed by driving the motor at a rather high speed for each specified interval. Thus, the service life of the ultrasonic motor can be increased.
