直(zhi)流(liu)(liu)電(dian)(dian)動(dong)機(ji)是依(yi)靠直(zhi)流(liu)(liu)電(dian)(dian)驅動(dong)的(de)(de)(de)電(dian)(dian)動(dong)機(ji)，在小型電(dian)(dian)器上應(ying)用較為(wei)廣泛。以下為(wei)直(zhi)流(liu)(liu)電(dian)(dian)動(dong)機(ji)的(de)(de)(de)工作原理圖(tu):此為(wei)一個簡單的(de)(de)(de)直(zhi)流(liu)(liu)電(dian)(dian)（D.C.）電(dian)(dian)動(dong)機(ji)。 

直流無刷電(dian)(dian)機(ji)(ji)(ji)的(de)(de)控(kong)制原(yuan)理(li)，要讓電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)(zhuan)動起(qi)來，首(shou)先控(kong)制部(bu)就必須根據hall-sensor感應到(dao)的(de)(de)電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)(zhuan)子(zi)(zi)目前所在位(wei)置(zhi)，然后依照定子(zi)(zi)繞線決定開(kai)(kai)啟(qi)(或關(guan)閉)換流器(inverter)中(zhong)功(gong)率(lv)晶體(ti)(ti)(ti)管的(de)(de)順序，inverter中(zhong)之AH、BH、CH(這些稱為上臂功(gong)率(lv)晶體(ti)(ti)(ti)管)及AL、BL、CL(這些稱為下(xia)臂功(gong)率(lv)晶體(ti)(ti)(ti)管)，使電(dian)(dian)流依序流經電(dian)(dian)機(ji)(ji)(ji)線圈產生(sheng)順向(或逆向)旋轉(zhuan)(zhuan)磁(ci)(ci)場，并與轉(zhuan)(zhuan)子(zi)(zi)的(de)(de)磁(ci)(ci)鐵相互作用，如此就能使電(dian)(dian)機(ji)(ji)(ji)順時/逆時轉(zhuan)(zhuan)動。當電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)動到(dao)hall-sensor感應出(chu)另一(yi)組信號的(de)(de)位(wei)置(zhi)時，控(kong)制部(bu)又(you)再開(kai)(kai)啟(qi)下(xia)一(yi)組功(gong)率(lv)晶體(ti)(ti)(ti)管，如此循環(huan)電(dian)(dian)機(ji)(ji)(ji)就可以依同(tong)一(yi)方向繼(ji)續轉(zhuan)(zhuan)動直到(dao)控(kong)制部(bu)決定要電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)(zhuan)子(zi)(zi)停(ting)止則關(guan)閉功(gong)率(lv)晶體(ti)(ti)(ti)管(或只開(kai)(kai)下(xia)臂功(gong)率(lv)晶體(ti)(ti)(ti)管)；要電(dian)(dian)機(ji)(ji)(ji)轉(zhuan)(zhuan)子(zi)(zi)反(fan)向則功(gong)率(lv)晶體(ti)(ti)(ti)管開(kai)(kai)啟(qi)順序相反(fan)。
