摘要：
We theoretically investigate the driving mechanism of a travelling wave ultrasonic motor that consists of a rotor and a stator, in consideration of the rotor vibration. As a result, we can make clear the inverse rotation phenomenon of the ultrasonic motor that could not be analyzed out of consideration of its vibration. And also, it is found that the driving characteristics are classified into six patterns clue to the rotor vibration and that, in the case that the phase of the rotor vibration is opposite to that of the stator, the driving force becomes generally greater than in the case of the same phase. Furthermore, it is experimentally confirmed that, in the case of same phase, the rotating direction is normal ( opposite to a travelling wave direction ) if the amplitude of the rotor vibration is smaller than that of the stator. © 2013 The Japan Society of Mechanical Engineers.
