三相定子繞組疊加產(chǎn)生一個旋轉(zhuǎn)的磁場，吸引著轉(zhuǎn)子追著不斷旋轉(zhuǎn)的磁場一直轉(zhuǎn)。

關(guān)于這三個定子繞組是怎么產(chǎn)生旋轉(zhuǎn)磁場的，大家看這張動圖時，需要同時具備“空間”和“時間”兩個視角。

從空間上來看，ABC三相繞組在360度空間上依次排開，空間上的相位差為120度，這是一目了然的。

從時間上來看，ABC三相繞組電壓的波形在時間上相差了三分之一個周期，比如說繞組電壓的頻率為50Hz，一個時間周期對應(yīng)20毫秒，ABC三相在時間上便是各自相差了6.67毫秒。

空間位置相差120度、時間相位相差三分之一個周期的三個正弦型的繞組電壓，合成的空間電壓矢量便是一個幅值恒定、旋轉(zhuǎn)頻率等于繞組電壓頻率的圓形軌跡。

考慮到有的瓜友想燒燒腦，在這里，筆者用一些簡單的初中數(shù)學(xué)，給大家做一個推導(dǎo)。
