基于弯振模态的螺纹杆式直线超声电机
LEAD SCREW LINEAR ULTRASONIC MOTOR USING BENDING VIBRATION MODES
摘要
Abstract
The operating principle of a lead screw linear ultrasonic motor using bending vibration modes is analyzed. The simplified beam bending vibration model is used to analyze the dynamics characteristics of the motor.Motion trajectory equations are derived for driving points of the stator. The motor operation and driving mechanisms are investigated. The vibration modes and the construction of the motor are analyzed by using the finite element method (FEM). A prototype motor is built and its stator dimension is 13 mm ×13 mm ×30 mm. The motor is experimentally characterized and the maximum output force of 5. 2 N is obtained.关键词
