armature mmf 中文意思是什麼
armature mmf
解釋
電樞磁動勢-
As a consequence, the mmf due to the armature current is along the aixs midway between the two adjacent poles, called the quadrature ( or q ) aixs
因此，由電樞電流所產生的磁動勢沿著相臨的兩個磁極，並稱為正交軸。 -
A commutator - brush combination is used as a mechanical rectifier to make the armature terminal voltage unidirectional and also to make the mmf wave due to the armature current fixed in space
通過使用換流器電刷的組合作為一個機械整流器以使得電樞的端電壓為單方向的同時也使得由電樞電流所產生的磁動勢在空間是固定的。 -
Abstract : first, the key magnet statuses and their pertinent mmf. position of exterior rotor brushless dc motor are described in this paper. second, the air - gap magnetic field and the armature reaction of the three - phase six - step exterior rotor brushless dc motor used in electrical bicycle are analyzed by means of mmf. vector, mmf. integration and magnetic field fem respectively. some valuable conclu - sions for designing this kind of motor are obtained
文摘:給出了外轉子無刷直流電動機的典型磁狀態及其對應的磁勢矢量位置，並用磁勢矢量合成法、磁勢積分法及電磁場的有限元方法對電動自行車用三相六狀態外轉子無刷直流電動機的氣隙磁場及電樞反應進行了詳盡的分析，從而得到有益於該種電機設計的結論。
