Marka la barbardhigo matoorka DC iyo matoorka aan isku mid ahayn, astaamaha farsamo ee muhiimka ah ee matoorka Brushless DC waa:

1. Astaamaha hawlgalka ee matoorka DC waxaa lagu helaa xakamaynta elektaroonigga ah. Waxay leedahay xakamayn wanaagsan iyo xawaare ballaaran.

2. Macluumaadka jawaab celinta booska Rotor iyo darawalka inverter-ka badan ee elektaroonigga ah ayaa loo baahan yahay.

3. Asal ahaan, matoorka AC wuxuu ku shaqeyn karaa xawaare sare isagoon lahayn dab iyo xoqid burush iyo qalab kale. Waxay leedahay isku halayn sare, cimri dheer oo shaqo ah mana u baahna dayactir.

4. Matoorka DC ee aan cadarka lahayn wuxuu leeyahay awood sare, ma jiro wax khasaare ah oo ku yimaada rotor-ka iyo kulaylka, iyo hufnaan sare: marka la barbar dhigo xogta, hufnaanta matoorka aan isku midka ahayn ee 7.5 kW waa 86.4%, hufnaanta matoorka DC ee aan cadarka lahaynna waxay gaari kartaa 92.4%.

5. Waa inay jiraan qaybo kontarool elektaroonik ah, wadarta kharashka ayaa ka sarreeya matoorka DC.

Waxaa inta badan jira laba nooc oo matoorro ah oo loo isticmaalo nidaamka AC: matoorka soo-kicinta iyo matoorka joogtada ah ee magnet synchronous. Matoorka joogtada ah ee magnet synchronous waxaa loo qaybin karaa matoorka joogtada ah ee magnet synchronous EMF (PMSM) iyo matoorka wareega ee EMF brushless DC (BLCDCM) iyadoo loo eegayo mabda'a shaqada ee kala duwan. Si ay u kala duwanaadaan hadda wadista iyo qaabka xakamaynta.

EMF-ga dambe ee matoorka isku-xidhka magnet-ka joogtada ah ee sinusoidal waa sinusoidal. Si matoorku u soo saaro wareegga siman, hadda socda ee dhex mara wareegga matoorka waa inuu ahaadaa sinusoidal. Sidaa darteed, calaamadda booska rotor-ka ee joogtada ah waa in la ogaadaa, inverter-kuna wuxuu matoorka siin karaa danab sinusoidal ama hadda. Sidaa darteed, PMSM waxay u baahan tahay inay qaadato danab sare ama hadda. Xallinta encoder-ka booska ama xaliyaha sidoo kale aad ayay u adag tahay.

BLDCM uma baahna dareemaha booska ee xallinta sare leh, qalabka jawaab celinta waa mid fudud, algorithm-ka xakamayntana waa mid fudud. Intaa waxaa dheer, garoon birlab ah oo hawada u jira oo hirarka trapezoidal ee BLDCM ah ayaa ka waxtar badan kan hirarka sinusoidal ee PMSM, cufnaanta awoodda BLDCM-na way ka sarreysaa kan PMSM. Sidaa darteed, codsiga iyo cilmi-baarista matoorka DC ee aan lahayn birlab joogto ah ayaa helay fiiro gaar ah oo aad u badan.
