摘　　要：分析了超声马达的运行机理、椭圆运动的生成过程以及超声马达的结构和性能.通过对三相驱动的平板弯曲超声马达的研究,论证了弯曲振动行波形成的条件.结果表明,三个相位差为120°的振动波也可以合成椭圆振动.The working mechanism of ultrasonic motor as well as ellipse movement that decide the performance and the structure of ultrasonic motor have been analyzed. Through the research of the flexural vibration ultrasonic motor of plain plate of travelling wave of three-phase drive, the condition that flexural vibration travelling wave forms have been proved , and shown as a result that the vibration wave of 3 phase differences (θ=120°) can also make up ellipse vibration.
