【摘要】 有关超声电机的建模、性能预估等理论问题的研究起步较晚 ,至今尚不完善和成熟。文中以旋转行波型超声电机为主线 ,在阐述超声电机机电耦合系统构成的基础上 ,比较全面地综述了国内外超声电机的建模方法 ,为进一步研究超声电机提供参考。更多还原

【Abstract】 The modeling and the property estimation theory f or ultrasonic motors is an open research problem and developing.In this paper,th e rotational ultrasonic motor using traveling wave is employed as an example to describe the electromechanical coupled wystem of ultrasonic motor systematically .Its modeling methods both at home and abroad are reviewed so as offer guide for the further on the motor.更多还原
