| Abstract: | Research on rod-type miniature piezoelectric ultrasonic motor was briefly reviewed in this paper.A new rod-type miniature piezoelectric ultrasonic motor based on free-shaft-fixed bending vibration mode with improved construction design was introduced in detail.The motor's vibration modes and driving mechanism were explained using the finite-element method.The vibration mode of motor stator,effects of slots on stator,position of piezoelectric plate and mode merge were investigated and simulation results were listed. |
