We propose miniature ultrasonic motors using stators made of a single bulk piezoelectric element. The bulk piezoelectric stator has the potential to increase output by reducing the dissipation that occurs in the adhesion layer between the PZTs and a metallic component in the stator. In this paper, we build two kinds of bulk piezoelectric stators: a cubic bulk stator with a side length of 4.2 mm and a hole of 3 mm in diameter, and a cylindrical bulk stator with an outer diameter of 4.2 mm and the same hole diameter. We evaluate their electrical and mechanical characteristics, such as impedance and vibration velocity. The experiments clarify the advantages of the bulk piezoelectric stators, such as low dissipation. The cubic bulk stator, which shows higher performance than the cylindrical one, is compared with a similar-shaped stator using a bronze cube and thin piezoelectric plates. The performance measures of the cubic bulk ultrasonic motor are optimized by the preload between the stator and rotor.

基于体压电元件的超声波电机的特性

我们提出使用由单个整体压电元件制成的定子的微型超声波马达。体压电定子具有通过减少在PZT和定子中的金属部件之间的粘合层中发生的耗散而增加输出的潜力。在本文中,我们构建了两种块状压电定子:一个边长为4.2 mm且直径为3 mm的孔的立方块状定子,以及一个外径为4.2 mm且孔径相同的圆柱状块状定子。我们评估它们的电气和机械特性,例如阻抗和振动速度。实验阐明了大体积压电定子的优点,例如低耗散。立方块状定子,其性能比圆柱形定子高,与使用青铜立方体和薄压电板的类似形状的定子进行比较。立方块体超声波电动机的性能指标是通过定子和转子之间的预载来优化的。
