因為繞組是固定的，所以可以建立連接來為它們供電。為了使固定繞組移動永磁體，繞組需要以受控順序通電（或換向）以產(chǎn)生旋轉磁場。

　　由于定子產(chǎn)生的旋轉磁場使轉子以相同的頻率旋轉，因此 BLDC 電機被稱為“同步”型。BLDC 電機可以是一相、二相或三相。三相 BLDC 電機是常見的，將成為本文其余部分的主題。

　　BLDC 電機控制

　　到目前為止，向三相 BLDC 電機順序施加電流的常見配置是使用以橋式結構排列的三對功率 MOSFET，如圖 2 所示。每對功率 MOSFET 控制電機一相的開關。在典型布置中，高側 MOSFET 使用脈寬調制 （PWM） 進行控制，脈寬調制 （PWM） 將輸入直流電壓轉換為調制驅動電壓。PWM 的使用可以限制啟動電流并提供對速度和轉矩的控制。PWM 頻率是在高頻發(fā)生的開關損耗和低頻發(fā)生的紋波電流之間進行權衡，在極端情況下，可能會損壞電機。通常，設計人員使用的 PWM 頻率至少比大電機轉速高一個數(shù)量級。
