Patent number: 5644199Abstract: The present invention relates to a method for driving an ultrasonic motor of the type which includes a vibrator for causing a flexural vibration wave in response to a pair of AC driving voltage signals, and a rotor in contact with the vibrator and moved by the flexural vibration wave. The rotational speed of the ultrasonic motor is controlled by using a feedback signal and a data table, the feedback signal indicating the current rotational speed of the ultrasonic motor, and the data table storing values of the feedback signal as a standard function of the rotational 21 speed. The method includes the step of sampling the feedback signal and detecting the rotational speed in a plurality of rotation states of the ultrasonic motor. The method obtains an approximate function representing the relationship between the sampled feedback signal and the detected rotational speed of the ultrasonic motor, and calculates correction coefficients for adjusting the approximate function to the standard function.Type: GrantFiled: July 18, 1995Date of Patent: July 1, 1997Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Nojima, Masanori Sumihara, Tetsuro Otsuchi, Takahiro Nishikura, Osamu Kawasaki, Katsu Takeda, Katsumi Imada
