摘要：

为了解决传统行波型超声波电机转速不高、效率低下且加工要求高的问题,提出一种新型锥面结构的行波型超声波电机.锥面电机采用锥面转子代替平面转子,定、转子之间的接触部分从上下平面过渡到内外侧锥面,并通过板簧实现接触面的偏心补偿.介绍适合锥面电机的定子结构,通过对定子内外侧锥角进行一系列的实验研究找到锥面超声波电机最适合的尺寸,采用ANSYS软件仿真发现,优化后的锥面定子最大振幅集中在定、转子接触部分,从而实现能量的高效传播.合理设计板簧尺寸,既补偿了定转子运行过程中出现的偏心现象,又在一定程度上大大简化了电机加工工序.研制直径为30 mm的行波型超声波电机样机,实验结果表明,该锥面超声波电机空载转速高达400 r/min,堵转力矩达到0.08 N·m.
Abstract:

A new sonic section traveling ultrasonic was proposed to avoid the shortcomings such as lowspeed, lowefficiency and rigor traveling conditions of traditional ultrasonic motor. This motor used the conic rotor instead of plane rotor and made the contact interface inside the stator. The leaf spring was used to compensate the eccentricity phenomena. Then the stator’s structure was presented. A lot of experiments were conducted to determine the best conic angle both inside and outside of the stator. The ANSYS software was used to find the largest amplitude focusing on the contacting face with the rotor for conic motor. An optional configuration with leaf spring was presented to compensate the eccentricity phenomena between stator and rotor during working and predigest the working procedure. The performance of this motor with the diameter of 30 mm was obtained through the experiment and funded the max speed increasing up to 400 r/min, the max toque reaching 0.08 N·m.
