low inertia motor 中文意思是什麼
low inertia motor
解釋
低慣性電動機-
Design engineers now selecting pmbldc motors over conventional dc or induction motor drives for the following reasons : 1 ) the absence of brushes results in an essentially maintenance free operation and eliminates the undesirable effects of commutation such as sparks, brush - loss, radio - frequency interference, etc. 2 ) the low inertia of the rotor enhances the quality of the mechanical response of the motor, shortening the acceleration and deceleration time. 3 ) utilizing rare - earth permanent magnet materials with high coercive force results in substantially higher efficiency than their counterpart with brushes of the same size. 4 ) because of the absence of commutation segments, the stator construction is simple
現在的工程師們更為青睞永磁無刷直流電動機是因為以下幾點原因： （ 1 ）去除了電刷的永磁無刷直流電動機徹底地免除了維護而且消除了我們不希望的由於換向帶來的火花、電刷損耗以及無線電干擾等等； （ 2 ）低轉動慣量的轉子提高了電機機械響應的質量，從而縮短了電機加速和減速的時間； （ 3 ）高矯頑力稀土永磁材料的使用使得同樣尺寸的永磁無刷直流電動機比傳統的直流電動機效率高； （ 4 ）由於沒有機械換向部分定子的結構簡單了。 -
However, by comparison with flap nozzle servo valve which has been used widely and popularly by now, the torque motor of jet pipe servo valve has a larger rotary inertia. this causes low natural frequency of servo valve, and thus the response speed of jet pipe servo valve is slow. moreover, the jet pipe of servo valve has large flexibility, and it is easy to excite oscillations and noise in the valve, which is named self - excited oscillations and noise
然而與目前普遍使用的噴嘴擋板伺服閥相比，射流管伺服閥的銜鐵組件轉動慣量大，導致力矩馬達部分固有頻率低，從而響應速度慢，此外，射流管供油管柔性大，容易產生自激現象，這些缺點都使得射流管伺服閥的動態特性差，從而影響了它的工作性能。 -
Abstract : in the light of the problems of high power consumption and low working efficiency in a beam pumping unit, a new method for power saving of the unit is proposed, that is, adopting an optimum structure of the unit and decreasing the periodic load coefficient of the pumping unit by changing the performance characteristics of the electric motor and by increasing the rotary inertia of the unit
