技術摘要:
This invention presents the design of a spherical piezoelectric motor utilizing three ceramic units as stators to enable omnidirectional motion. The motor operates under resonance conditions, and a specific electrode configuration technique is employed to enhance vibration amplitude and improve efficiency during lateral excitation. PZT-4 ceramic material is chosen as the actuator, and servomotors are used to adjust the stator-rotor contact point, enabling both clockwise and counterclockwise rotation. By varying the magnitude ratio of the applied signals to the ceramics, the rotor's orientation can be adjusted, allowing for movement along the 𝒙𝒛, 𝒙𝒚, and 𝒚𝒛 planes, which is a key advantage of the proposed model. The motor is capable of producing an optimal output of 37 rpm when excited with a 12.4 kHz signal at a voltage of 35 V.
