有刷直流 (BDC)

有刷直流 (BDC) 馬達從用於換向的「刷子」而得名。有刷直流馬達經常用於家用電器與車輛。其也在工業領域中佔有穩固的地位,因為具備有刷馬達獨有變更扭矩對速度比率的能力。BDC 的控制簡易,因為速度與扭矩和施加的電壓/電流成比例。


有刷直流馬達包含 4 個基本元件:定子、轉子 (或電樞)、刷子與整流器。轉子也稱為電樞,是由一或多個線圈構成。這些線圈通電時就會產生磁場。此轉子場的磁極會被吸引到定子產生的相反極,使轉子旋轉。在馬達旋轉時,線圈持續以不同的順序來通電,讓轉子產生的磁極不會超過定子產生的磁極。轉子線圈中磁場的切換稱為「換向」。可透過反轉刷子的極性 (亦即將電池的引線反轉) 而輕易反轉旋轉的方向 (順時針及/或逆時針)。


BDC 馬達有四種類型。永久磁鐵有刷直流馬達、並激有刷直流馬達、串激直流馬達,第四種是複激有刷直流馬達,這是並激與串激有刷直流馬達的組合。
