基于纵扭型超声电机与行波型超声电机发展存在的问题,笔者分别从超声电机的驱动机理、压电陶瓷逆压电效应的能量转换以及定、转子之间的接触形式三个方面对两种电机进行了详细的分析比较,指出了纵扭型超声电机比行波型超声电机对提高超声电机的性能更具有潜在的优势;同时指明当前阻碍纵扭型超声电机发展的几点不利因素.最后,从发展的角度说明了纵扭型超声电机的发展前景是非常美好的.
Based on current development of the ultrasonic-motor using longitudinal and torsional vibration modes and the traveling-wave ultrasonic-motor,this paper analye them in detail from three aspects:driving mechanics of the ultrasonic-motor,energy conversion based on convert piezoelectric effect of piezoelectric ceramic and contact form between stator and rotor;it points out that the ultrasonic-motor using longitudinal and torsional vibration models has more dominance to improve performance of the motor than the...
