無刷直流 (BLDC)

無刷直流 (BLDC) 馬達也稱為電子換向馬達。轉子上無刷,換向是在某些轉子位置上以電子方式進行。BLDC 馬達是具備獨特反電動勢波形的永磁同步馬達,使其行為類似於有刷直流馬達。BLDC 馬達不是直接以直流電壓電源來操作。但是其基本操作原理類似於直流馬達。


無刷直流馬達具備含永久磁鐵的轉子,以及含線圈的定子;BLDC 馬達基本上就是翻轉直流馬達。沒有刷子與整流器,線圈連接到控制電子裝置。控制電子裝置取代了整流器的功能,並將適當的線圈通電。通電方式會使線圈繞著定子旋轉,通電的定子線圈會引導轉子磁鐵,並在轉子對齊定子時切換。


無刷直流馬達最適合需要高可靠度、高效率、高單位工作容積功率的各種應用。一般而言,BLDC 馬達被視為能在寬廣的速度範圍中提供大量扭矩的高效能馬達。
