| 摘 要： | 以振动片式驻波超声波电机为研究对象,设计并制作两台不同结构尺寸的样机,就不同倾角振动片对电机性能的影响进行对比实验.结果发现,振动片的角度值也存在一个最优的匹配范围,预压力有一个最佳的匹配值,以及换能器的预紧力大小对电机输出的影响十分敏感.在一定条件下(如驱动频率、振动片倾角、定转子间的预压力等),振动片式驻波超声波电机能够实现转子的反转效果.说明一般认为该类型电机只能单向驱动的结论并不准确.此外,转子的正反转效果与驱动频率、振动片倾角、定转子间预压力等因素有关.

| Abstract: | Taking the ultrasonic motor with vibrating reeds as the research object,2 prototypes of this kind of motor with different structural parameters are designed and built,and comparative experiments about the influence of the vibrating reeds with different oblique angles on the characteristics of the motors are conducted.The experimental results have shown that there is an optimal range for the values of the oblique angles of vibrating reeds and an optimal value for the pre-pressure,and that the influence of th... |
