電機更。它保持其，而等效的傳統(tǒng)電機的效率和功率因磨損而下降，導致電刷接觸不良，電刷和換向器之間的電弧耗散能量，以及影響導電性的污垢。

　　更高的效率允許 BLDC 電機在給定的功率輸出下做得更小、更輕、更安靜，從而進一步提高其在汽車等領域的普及度；白色家電；以及供暖、通風和空調(diào) （HVAC）。BLDC 電機的其他優(yōu)點包括的速度與扭矩特性（啟動時的扭矩除外）、更動態(tài)的響應、無噪音運行和更高的速度范圍。

　　BLDC 電機的缺點是其復雜性以及相關的成本增加。電子換向需要監(jiān)控電路來確保線圈通電的定時，以實現(xiàn)的速度和轉(zhuǎn)矩控制，并確保電機以率運行。

　　幸運的是，這個領域正在迅速成熟，硅供應商現(xiàn)在提供各種高度集成的 BLDC 電機驅(qū)動器功率 MOSFET 芯片，帶有外部或嵌入式微控制器，以簡化設計過程，同時降低組件成本。本文將解釋設計人員如何利用這些新芯片來簡化設計過程
