表面粒子計(jì)數(shù)器 - being a sort of new principle micromotor in the fronitier of science, the ultrasonic motor ( usm ) is developed at recently twenty years . utilizing the stator surface particle elliptical motion excited by piezoceeramics, the usm is drived by friction force between the stator and rotor
本文以這一新型電動(dòng)機(jī)為研究對(duì)象，對(duì)其運(yùn)行特性和控制策略進(jìn)行研究，是有較重要的理論和實(shí)際意義的。 - being a sort of new principle micromotor in the fronitier of science . the ultrosonic motor ( usm ) is developed at recently twenty years . utilizing the stator surface particle elliptical motion excited by piezoceeramics, the usm is drived by friction force between the stator and rotor . compared with the conventional electromagnetic motor, the ultrasonic motor has the following features : high speed, high holding torque when power is off and so on . because of it's characteristics, the ultrasonic motor has obtained some widespread application in robots, precise instrument, house electronical appliance, sapceecraft automobile and micromechanism
超聲波電機(jī)(ultrasonicmotor)是近二十年來發(fā)展起來的一種新原理電機(jī)，其原理不同于傳統(tǒng)的電磁型電機(jī)，它是利用壓電陶瓷的逆壓電效應(yīng)使定子的表面質(zhì)點(diǎn)產(chǎn)生橢圓運(yùn)動(dòng)，通過定子和轉(zhuǎn)子之間的摩擦力驅(qū)動(dòng)轉(zhuǎn)子運(yùn)動(dòng)。這種新型的電機(jī)與傳統(tǒng)電磁電機(jī)相比，具有響應(yīng)快、不受電磁干擾、結(jié)構(gòu)緊湊、低速、大扭矩、斷電自鎖等優(yōu)點(diǎn)，因而在微型機(jī)械、機(jī)器人、精密儀器、家用電器、航天器、汽車等方面顯示出廣泛的應(yīng)用前景。 - It's difficult to find surface particle in a sentence. 用surface particle造句挺難的
